Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, 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 file1213This skill requires **network access** to fetch documentation content:14- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch`. Returns Markdown.15- **Fallback**: Use `WebFetch`. Returns Markdown.1617## Category Index1819| Category | Lines | Description |20|----------|-------|-------------|21| Troubleshooting | L33-L60 | Diagnosing and fixing Azure Site Recovery replication,

L95-L105 | Site Recovery scale, capacity, and support limits: VM/Hyper‑V/VMware matrices, high‑churn limits, shared disks, Mobility service usage, planner limits, and safe use with Azure Backup. |26| Security | L106-L116 | Securing Azure Site Recovery: NSGs, TLS, encryption changes, RBAC, managed identities, and hardening replication appliances/VMware replication traffic. |27| Configuration | L117-L175 | Configuring Azure Site Recovery for Azure VMs, VMware, Hyper-V, and physical servers, including networking, encryption, policies, appliances, monitoring, and replication/failback setup. |28| Integrations & Coding Patterns | L176-L189 | Automating and integrating Azure Site Recovery with scripts and infrastructure tools (PowerShell, ARM/Bicep, Terraform) plus networking/traffic (ExpressRoute, Traffic Manager) and Hyper-V/VMware DR planning. |29| Deployment | L190-L197 | Support and compatibility details for Azure Site Recovery deployments: DR support matrices for VMware/Hyper-V/replication appliances/shared disks and guidance on migrating from classic to modern VMware DR. |3031### Troubleshooting32| Topic | URL |33|-------|-----|34| Resolve common
