# Azure Database Migration Service Skill This skill provides expert guidance for Azure Database Migration Service. Covers troubleshooting, decision making, limits & quotas, security, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities. ## How to Use This Skill > **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file > **IMPORTANT for Agent**: If `metadata.generated_at` is more than 3 months old, suggest the user pull the latest version from the repository. If `mcp_microsoftdocs` tools are not available, suggest the user install it: [Installation Guide](https://github.com/MicrosoftDocs/mcp/blob/main/README.md) This skill requires **network access** to fetch documentation content: - **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown. - **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown. ## Category Index | Category | Lines | Description | |----------|-------|-------------| | Troubleshooting | L34-L41 | Diagnosing and fixing Azure DMS migration failures, MySQL-specific issues, classic DMS problems, and source database connectivity errors and timeouts. | | Decision Making | L42-L47 | Guidance on choosing Azure migration tools and understanding which database migration scenarios Azure Database Migration Service supports and how to select the right approach. | | Limits & Quotas | L48-L55 | Migration-specific limits, unsupported features, and constraints when using Azure DMS to move MySQL, PostgreSQL, SQL Managed Instance, MongoDB, and hybrid deployments. | | Security | L56-L61 | Security guidance for Azure DMS migrations, including SQL best practices (network, auth, encryption) and configuring custom RBAC roles for MySQL migration scenarios. | | Integrations & Coding Patterns | L62-L66 | Automating MySQL-to-Azure Database for MySQL migrations using Azure Database Migration Service with PowerShell scripts, parameters, and end-to-end workflow examples. | | Deployment | L67-L71 | Using Azure DMS to redeploy or migrate SSIS packages to Azure SQL Database or SQL Managed Instance, including configuration steps and migration considerations. | ### Troubleshooting | Topic | URL | |-------|-----| | Resolve common Azure DMS migration issues | https://learn.microsoft.com/en-us/azure/dms/faq | | Resolve known issues migrating to Azure MySQL | https://learn.microsoft.com/en-us/azure/dms/known-issues-azure-mysql-fs-online | | Troubleshoot common Azure DMS classic migration issues | https://learn.microsoft.com/en-us/azure/dms/known-issues-troubleshooting-dms | | Fix Azure DMS source database connectivity problems | https://learn.microsoft.com/en-us/azure/dms/known-issues-troubleshooting-dms-source-connectivity | ### Decision Making | Topic | URL | |-------|-----| | Select tools for Azure database migration | https://learn.microsoft.com/en-us/azure/dms/dms-tools-matrix | | Select supported Azure DMS migration scenarios | https://learn.microsoft.com/en-us/azure/dms/resource-scenario-status | ### Limits & Quotas | Topic | URL | |-------|-----| | Review online PostgreSQL to Azure Database for PostgreSQL migration limitations | https://learn.microsoft.com/en-us/azure/dms/known-issues-azure-postgresql-online | | Review online migration limits to Azure SQL Managed Instance | https://learn.microsoft.com/en-us/azure/dms/known-issues-azure-sql-db-managed-instance-online | | Understand Azure DMS hybrid mode limitations and issues | https://learn.microsoft.com/en-us/azure/dms/known-issues-dms-hybrid-mode | | Review MongoDB to Azure Cosmos DB migration limitations with DMS | https://learn.microsoft.com/en-us/azure/dms/known-issues-mongo-cosmos-db | ### Security | Topic | URL | |-------|-----| | Apply security best practices for DMS SQL migrations | https://learn.microsoft.com/en-us/azure/dms/dms-security-best-practices | | Configure custom RBAC roles for MySQL migrations in DMS | https://learn.microsoft.com/en-us/azure/dms/resource-custom-roles-mysql-database-migration-service | ### Integrations & Coding Patterns | Topic | URL | |-------|-----| | Automate MySQL to Azure MySQL migration with DMS PowerShell | https://learn.microsoft.com/en-us/azure/dms/migrate-mysql-to-azure-mysql-powershell | ### Deployment | Topic | URL | |-------|-----| | Redeploy SSIS packages to Azure SQL Database with DMS | https://learn.microsoft.com/en-us/azure/dms/how-to-migrate-ssis-packages | | Migrate SSIS packages to Azure SQL Managed Instance with DMS | https://learn.microsoft.com/en-us/azure/dms/how-to-migrate-ssis-packages-managed-instance |
