# Migrations

Guidance for migrations from legacy data platforms to Azure Databricks. Start with the general
migration guide. Then, use a source guide for its platform, language, and tool differences.

These pages use the platform architecture and operations guidance from this knowledge base.

## Migration guides

- [Databricks migration guide](migration-playbook.md) — six migration phases, strategy choices,
  validation, rollback, and the technical sequence.
- [SQL Server to Databricks](sql-server-to-databricks.md) — T-SQL conversion, data type mapping,
  and migration from SSIS or SQL Server Agent to Lakeflow.
- [Azure Synapse to Databricks](azure-synapse-to-databricks.md) — dedicated SQL pools, Synapse
  pipelines, serverless SQL, and Spark workloads.
