Azure Upgrade
This skill handles assessment and automated upgrades of existing Azure workloads from one Azure service, hosting plan, or SKU to another — all within Azure. This includes plan/tier upgrades (e.g. Consumption → Flex Consumption), cross-service migrations (e.g. App Service → Container Apps), and SKU changes. It also covers Azure SDK for Java source-code modernization (e.g. legacy Javacom.microsoft.azure.*→ moderncom.azure.*). This is NOT for cross-cloud migration — useazure-cloud-migratefor that.
Triggers
| User Intent | Example Prompts |
|---|---|
| Upgrade Azure Functions plan | "Upgrade my function app from Consumption to Flex Consumption" |
| Change hosting tier | "Move my function app to a better plan" |
| Assess upgrade readiness | "Is my function app ready for Flex Consumption?" |
| Automate plan migration | "Automate the steps to upgrade my Functions plan" |
| Modernize legacy Azure Java SDK | "Migrate legacy Azure SDKs for Java", "Upgrade legacy Azure Java SDK", "Migrate my Java project from com.microsoft.azure to com.azure" |
Rules
- Follow phases sequentially — do not skip
- Generate an assessment before any upgrade operations
- Load the scenario reference and follow its rules
- Use
mcp_azure_mcp_get_azure_bestpracticesandmcp_azure_mcp_documentationMCP tools - Destructive actions require
ask_user— global-rules - Always confirm the target plan/SKU with the user before proceeding
- Never delete or stop the original app without explicit user confirmation
- All automation scripts must be idempotent and resumable
Upgrade Scenarios
| Source | Target | Reference |
|---|---|---|
| Azure Functions Consumption Plan | Azure Functions Flex Consumption Plan | consumption-to-flex.md |
Legacy Azure Java SDK (com.microsoft.azure.*) | Modern Azure Java SDK (com.azure.*) | languages/java/README.md |
SDK upgrade scenarios (e.g. Java legacy → modern) run a source-code modernization flow that is distinct from Azure service/plan/SKU upgrades: follow the scenario reference, not the Steps below.

MCP Tools
| Tool | Purpose |
|---|---|
mcp_azure_mcp_get_azure_bestpractices | Get Azure best practices for the target service |
mcp_azure_mcp_documentation | Look up Azure documentation for upgrade scenarios |
mcp_azure_mcp_appservice | Query App Service and Functions plan details |
mcp_azure_mcp_applicationinsights | Verify monitoring configuration |
Steps
- Identify — Determine the source and target Azure plans/SKUs. Ask user to confirm.
- Assess — Analyze existing app for upgrade readiness → load scenario reference (e.g., consumption-to-flex.md)
- Pre-migrate — Collect settings, identities, configs from the existing app
- Upgrade — Execute the automated upgrade steps (create new resources, migrate settings, deploy code)
- Validate — Hit the function app default URL to confirm the app is reachable, then verify endpoints and monitoring
- Ask User — "Upgrade complete. Would you like to verify performance, clean up the old app, or update your IaC?"
- Hand off to
azure-validatefor deep validation orazure-deployfor CI/CD setup
Track progress in upgrade-status.md inside the workspace root.
