Covers troubleshooting, decision making, limits & quotas, security, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.89## How to Use This Skill1011> **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 file1213> **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)1415This skill requires **network access** to fetch documentation content:16- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown.17- **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown.1819## Category Index2021| Category | Lines | Description |22|----------|-------|-------------|23| Troubleshooting | L34-L39 | Diagnosing and resolving Azure DMS classic migration failures and source DB connectivity issues (network, auth, firewall, TLS) during database migrations. |24| Decision Making | L40-L46 | Choosing the right Azure DMS tool and scenario for your source/target databases, plus FAQs on supported migrations, limitations, and how to use Azure Database Migration Service. |25| Limits & Quotas | L47-L55 | Migration-specific limits, unsupported features, and constraints when using Azure DMS to move MySQL, PostgreSQL, SQL Managed Instance, MongoDB, and hybrid deployments. |26| 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. |27| 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. |28| 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. |2930### Troubleshooting31| Topic | URL |32|-------|-----|33| Troubleshoot common Azure DMS classic migration issues | https://learn.microsoft.com/en-us/azure/dms/known-issues-troubleshooting-dms |34| Fix Azure DMS source database connectivity problems | https://learn.microsoft.com/en-us/azure/dms/known-issues-troubleshooting-dms-source-connectivity |3536### Decision Making37| Topic | URL |38|-------|-----|39| Choose database migration tools with the Azure DMS matrix | https://learn.microsoft.com/en-us/azure/dms/dms-tools-matrix |40| Answer common Azure Database Migration Service usage questions | https://learn.microsoft.com/en-us/azure/dms/faq |41| Select supported Azure DMS migration scenarios | https://learn.microsoft.com/en-us/azure/dms/resource-scenario-status |4243### Limits & Quotas44| Topic | URL |45|-------|-----|46| Review migration limitations to Azure Database for MySQL | https://learn.microsoft.com/en-us/azure/dms/known-issues-azure-mysql-fs-online |47| Review online PostgreSQL to Azure Database for PostgreSQL migration limitations | https://learn.microsoft.com/en-us/azure/dms/known-issues-azure-postgresql-online |48| 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 |49| Understand Azure DMS hybrid mode limitations and issues | https://learn.microsoft.com/en-us/azure/dms/known-issues-dms-hybrid-mode |50| Review MongoDB to Azure Cosmos DB migration limitations with DMS | https://learn.microsoft.com/en-us/azure/dms/known-issues-mongo-cosmos-db |5152### Security53| Topic | URL |54|-------|-----|55| Apply security best practices for DMS SQL migrations | https://learn.microsoft.com/en-us/azure/dms/dms-security-best-practices |56| Configure custom RBAC roles for MySQL migrations in DMS | https://learn.microsoft.com/en-us/azure/dms/resource-custom-roles-mysql-database-migration-service |5758### Integrations & Coding Patterns59| Topic | URL |60|-------|-----|61| Automate MySQL to Azure MySQL migration with DMS PowerShell | https://learn.microsoft.com/en-us/azure/dms/migrate-mysql-to-azure-mysql-powershell |6263### Deployment64| Topic | URL |65|-------|-----|66| Redeploy SSIS packages to Azure SQL Database with DMS | https://learn.microsoft.com/en-us/azure/dms/how-to-migrate-ssis-packages |67| 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 |
