****Cloud data migration tools** move databases, files and application data from on-premises systems or another cloud into AWS, Azure, Google Cloud, Oracle Cloud or a cloud data warehouse, with as little downtime and data loss as possible. The best ones copy the initial load, then keep source and target in sync with change data capture (CDC) until you cut over.

The best cloud data migration tools in 2026 are **Integrate.io** for low-code migrations with transformation and 60-second CDC into any cloud warehouse; the cloud providers' own services, **AWS Database Migration Service**, **Azure Database Migration Service**, **Google Cloud Database Migration Service** and **OCI Database Migration**, for moving databases onto their platforms; **BigQuery Data Transfer Service** for scheduled loads into BigQuery; and **Qlik Replicate** and **Striim** for enterprise real-time replication.

## Key Takeaways

* Integrate.io migrates data from 150+ sources into Snowflake, BigQuery, Redshift, Azure Synapse and databases, transforms it on the way with 220+ low-code steps, keeps it in sync with 60-second CDC until cutover, and offers migration tools for moving off SSIS, Fivetran, Informatica, Talend and Matillion, for a flat $1,999 a month.
* AWS DMS instances start at $0.018 an hour (t2.micro, single-AZ, US East), and DMS Serverless at about $0.08 per capacity-unit hour.
* Azure Database Migration Service offers a free tier for most migrations into Azure SQL, with Premium vCores billed hourly for larger online migrations.
* Cloud-native services move databases onto their own platform; they rarely transform data or handle SaaS sources, which is where an integration platform fills in.
* Migrating servers or whole workloads is a different job, handled by AWS Application Migration Service, Azure Migrate and Google Migrate to Virtual Machines.

## What Is Cloud Data Migration?

Cloud data migration is moving data from on-premises systems, legacy applications or another cloud into cloud storage, databases or a cloud data warehouse. It usually happens in three phases: an initial full load, ongoing change data capture to keep source and target in sync while applications still run on the old system, and a short cutover once the target is validated. See what is data migration.

Migration tools handle the parts that are hard to do by hand: connecting to the source, moving large volumes reliably, converting schemas and data types, capturing changes during the move, validating row counts and checksums, and reporting errors. Moving to the cloud gives teams elastic storage and compute, managed security and disaster recovery, and direct access to cloud analytics and AI services, but only if the data arrives complete, consistent and usable.

## How We Evaluated These Tools

* Sources and targets: which databases, applications, files and clouds each tool supports.
* Downtime: whether it supports online migration with ongoing CDC and a short cutover.
* Transformation and schema conversion: whether data can be cleaned, remapped or converted between engines during the move.
* Validation and monitoring: row counts, data validation, error handling and alerts.
* Pricing: published rates where vendors publish them, from the AWS and Microsoft price lists in October 2026; "quote" otherwise. We do not use review-site scores.

## The 8 Best Cloud Data Migration Tools in 2026

### 1. Integrate.io

Integrate.io is a low-code data pipeline platform that handles cloud migrations end to end: the initial load, transformation on the way, continuous replication until cutover, and the ongoing pipelines that keep the new cloud platform fed afterwards. Where cloud-native services move one database onto one provider, Integrate.io moves data from databases, SaaS applications and files into whichever cloud warehouse or database you are moving to.

**Best for:** data and operations teams migrating to Snowflake, BigQuery, Redshift, Azure Synapse or a cloud database who need data cleaned and remapped during the move, zero-downtime cutover, and the same platform for pipelines after go-live.

#### Why it is the best cloud data migration tool for data teams

* Zero-downtime cutover with CDC: change data capture every 60 seconds from Oracle, SQL Server, MySQL, PostgreSQL and other databases keeps the cloud target current while applications still run on the old system, with automatic schema handling and history mode.
* Transform during the move: 220+ low-code transformations (type conversions, schema restructuring, joins, lookups, deduplication, masking) plus SQL and Python, so data lands clean and analytics-ready instead of being fixed after the migration.
* 150+ connectors covering databases, warehouses, SaaS applications such as Salesforce and NetSuite, a universal REST connector for any API, and file ingestion from SFTP, cloud storage and email.
* Migration tools for legacy ETL: automated migration programs for moving pipelines off SSIS, Fivetran, Informatica, Talend and Matillion, with a Solution Engineer and a contract buyout where applicable.
* Salesforce migrations in both directions with Bulk API 2.0, upsert and External ID matching. See Salesforce data migration.
* Validation and alerts on row counts, failures, run times and schema changes, sent to email, Slack, Microsoft Teams, PagerDuty or a webhook.
* 24/7 support with a 2-minute average first response, a 92% customer satisfaction score and 30-day onboarding with a dedicated Solution Engineer.
* Security: annual SOC 2 audit, HIPAA with a BAA, GDPR and CCPA, SSH, reverse SSH and PrivateLink to on-premises databases, and a pass-through design in which no customer data is stored and ephemeral data is deleted within 24 hours.

#### Pricing

The Core plan is $1,999 a month with unlimited data volume, pipelines and connectors, so a one-time historical load of billions of rows costs the same as steady-state replication. The 14-day free trial needs no card.

### 2. AWS Database Migration Service (DMS)

AWS DMS migrates databases to and from AWS, for homogeneous moves (Oracle to Oracle) and heterogeneous ones (Oracle to Aurora PostgreSQL), with ongoing replication for minimal-downtime cutovers. DMS Schema Conversion converts schemas and code between engines, and DMS Serverless scales capacity automatically.

**Best for:** teams moving relational databases onto RDS, Aurora, Redshift, DynamoDB or S3.

**Limitations:** focused on databases; limited transformation; tuning replication instances and handling large LOBs takes AWS expertise. See AWS DMS challenges and solutions.

**Pricing (US East):** replication instances from $0.018 an hour (dms.t2.micro, single-AZ); DMS Serverless from about $0.082 per DMS capacity unit hour; storage and data transfer extra.

### 3. Azure Database Migration Service

Azure Database Migration Service is Microsoft's managed service for migrating SQL Server, MySQL, PostgreSQL and MongoDB workloads into Azure SQL Database, SQL Managed Instance, SQL Server on Azure VMs, Azure Database for PostgreSQL and MySQL, and Azure Cosmos DB, with offline and online modes. It is driven from the Azure portal and the Azure SQL migration extension.

**Best for:** SQL Server estates moving to Azure SQL.

**Limitations:** Azure targets only; schema conversion for non-Microsoft sources relies on separate tools; minimal transformation.

**Pricing:** a free tier covers most migrations; Premium capacity for larger online migrations is billed per vCore-hour (for example $0.308 an hour for 4 vCores in East US).

### 4. Google Cloud Database Migration Service

Google Cloud's Database Migration Service moves MySQL, PostgreSQL, SQL Server and Oracle databases into Cloud SQL and AlloyDB, with continuous migration for minimal downtime and a conversion workspace that converts Oracle schemas and code to PostgreSQL.

**Best for:** teams moving operational databases onto Google Cloud.

**Limitations:** Google Cloud targets only; heterogeneous conversions need review and testing.

**Pricing:** published on Google Cloud's pricing page; homogeneous and heterogeneous migrations are priced differently.

### 5. BigQuery Data Transfer Service

BigQuery Data Transfer Service schedules and manages loads into BigQuery from Google sources (Google Ads, YouTube, Google Analytics, Cloud Storage), other clouds (Amazon S3, Azure Blob Storage), data warehouses being migrated (Teradata, Amazon Redshift) and selected SaaS applications.

**Best for:** teams consolidating Google marketing data or migrating a warehouse into BigQuery.

**Limitations:** BigQuery is the only target; scheduled transfers rather than CDC; no transformation before load.

**Pricing:** varies by source on Google Cloud's BigQuery pricing page; many Google-owned sources have no transfer charge beyond BigQuery storage and query costs.

### 6. OCI Database Migration

OCI Database Migration is Oracle Cloud Infrastructure's managed service for moving Oracle and MySQL databases into Oracle Autonomous Database and other OCI databases, with offline migrations through Data Pump and online migrations kept in sync by Oracle GoldenGate.

**Best for:** Oracle estates moving to Oracle Cloud.

**Limitations:** designed around Oracle targets; GoldenGate configuration takes Oracle expertise.

**Pricing:** billed through Oracle Cloud; check Oracle's cost estimator for GoldenGate and target database charges.

### 7. Qlik Replicate

Qlik Replicate (formerly Attunity Replicate) is an enterprise replication engine with log-based CDC from a very wide range of sources, including SAP, mainframe and IBM Db2, into cloud warehouses, lakes, streams and databases, managed from a central console.

**Best for:** large enterprises migrating SAP or mainframe data to the cloud with continuous replication.

**Limitations:** enterprise licensing and implementation effort; limited transformation. See Qlik Replicate alternatives.

**Pricing:** quote.

### 8. Striim

Striim is a streaming integration platform with real-time CDC, in-flight processing in streaming SQL, and data validation through Validata, available as Striim Cloud (managed) or Striim Platform (self-hosted).

**Best for:** migrations where the target must stay within seconds of the source, with processing in flight.

**Limitations:** streaming architecture and pricing suit high-value real-time use cases more than one-off batch moves. See Striim alternatives.

**Pricing:** Striim Developer is free up to 25 million events a month; Striim Cloud and Striim Platform are quoted.

## Workload and Bulk Storage Migration Services

"Cloud migration tools" also covers moving servers, virtual machines and bulk files, which is a different job from migrating data:

* Servers and VMs: AWS Application Migration Service, Azure Migrate and Google Cloud's Migrate to Virtual Machines replicate whole servers into cloud instances, and AWS Migration Hub, Azure Migrate and Google's Migration Center track discovery and planning.
* Bulk files and storage: AWS DataSync, AWS Snowball, Azure Data Box, AzCopy and Google Storage Transfer Service move large file sets online or on physical devices.

Most programs use both: a workload migration service for applications and a data migration or integration tool for the databases and data feeds behind them. For AWS specifically, see AWS migration tools and AWS data management.

## How to Run a Cloud Data Migration

1. Inventory and assess. List every source, its size, change rate, dependencies and owners, and decide what moves, what is archived and what is retired.
2. Choose the pattern. Lift-and-shift the same engine, re-platform to a managed service, or re-architect into a cloud warehouse. Heterogeneous moves need schema and code conversion.
3. Pilot on a subset. Migrate a representative, non-critical dataset, then validate row counts, checksums, data types and edge cases such as nulls, time zones and character sets.
4. Run the full load, then CDC. Load history, then keep the target in sync with change data capture while users stay on the source system.
5. Validate and cut over. Reconcile source and target, freeze writes briefly, apply the last changes, switch applications, and keep the source read-only as a fallback.
6. Operate. Turn migration jobs into monitored production pipelines with alerts, and decommission the old system on a schedule.

For more detail, see data migration best practices.

## Mistakes to Avoid

* No inventory or plan: undocumented dependencies are the most common cause of broken cutovers.
* Big-bang cutovers without CDC: a full reload during a maintenance window risks long downtime and missed changes.
* Skipping validation: compare counts and checksums table by table before switching applications.
* Moving bad data: deduplicate, standardize and mask sensitive fields during the move rather than after.
* Weak security: encrypt in transit and at rest, use private connectivity, and limit migration credentials to the people who need them.
* No rollback: keep the source available and backed up until the target has run cleanly in production.

## FAQs

### What are the best cloud data migration tools?

The best cloud data migration tools in 2026 are Integrate.io, AWS Database Migration Service, Azure Database Migration Service, Google Cloud Database Migration Service, BigQuery Data Transfer Service, OCI Database Migration, Qlik Replicate and Striim. Integrate.io suits teams that need transformation, SaaS and file sources and 60-second CDC into any cloud warehouse; the cloud providers' services suit moving databases onto their own platform.

### How do I migrate data to the cloud without downtime?

Load the historical data first, then keep the target in sync with change data capture while applications keep running on the source. When the target is validated, pause writes briefly, apply the final changes and switch applications over. Integrate.io, AWS DMS, Azure DMS online mode, Google Cloud DMS, Qlik Replicate and Striim all support this pattern.

### What is the difference between cloud migration and cloud data migration?

Cloud migration covers moving applications, servers and infrastructure, using services such as AWS Application Migration Service, Azure Migrate and Google Migrate to Virtual Machines. Cloud data migration covers moving the data itself, such as databases, warehouses, files and SaaS data, using tools such as Integrate.io and AWS DMS.

### Which tools transform data during a cloud migration?

Integrate.io transforms data in the pipeline with 220+ low-code steps plus SQL and Python, so data lands cleaned and remapped. AWS DMS offers basic mappings and DMS Schema Conversion, Google Cloud DMS converts Oracle schemas to PostgreSQL, and Striim processes data in flight with streaming SQL. Most other cloud-native services move data as-is.

### How much do cloud data migration tools cost?

AWS DMS replication instances start at $0.018 an hour and DMS Serverless at about $0.08 per capacity-unit hour. Azure Database Migration Service has a free tier, with Premium vCores billed hourly. Striim Developer is free up to 25 million events a month. Integrate.io is $1,999 a month flat with unlimited data. Qlik Replicate, Striim Cloud and Oracle GoldenGate are quoted or billed through the cloud provider.

### How do I keep data secure during a cloud migration?

Encrypt data in transit and at rest, connect through private links, SSH tunnels or VPNs rather than public endpoints, restrict migration credentials with role-based access, mask sensitive fields during the move, and audit the target after cutover. Choose tools with SOC 2 and, where relevant, HIPAA coverage.
