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. This is NOT for cross-cloud migration — use azure-cloud-migrate for 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"

Rules

1. Follow phases sequentially — do not skip
2. Generate an assessment before any upgrade operations
3. Load the scenario reference and follow its rules
4. Use mcp_azure_mcp_get_bestpractices and mcp_azure_mcp_documentation MCP tools
5. Destructive actions require ask_user — global-rules
6. Always confirm the target plan/SKU with the user before proceeding
7. Never delete or stop the original app without explicit user confirmation
8. 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

No matching scenario? Use mcp_azure_mcp_documentation and mcp_azure_mcp_get_bestpractices tools to research the upgrade path.

MCP Tools

Tool	Purpose
mcp_azure_mcp_get_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

1. Identify — Determine the source and target Azure plans/SKUs. Ask user to confirm.
2. Assess — Analyze existing app for upgrade readiness → load scenario reference (e.g., consumption-to-flex.md)
3. Pre-migrate — Collect settings, identities, configs from the existing app
4. Upgrade — Execute the automated upgrade steps (create new resources, migrate settings, deploy code)
5. Validate — Hit the function app default URL to confirm the app is reachable, then verify endpoints and monitoring
6. Ask User — "Upgrade complete. Would you like to verify performance, clean up the old app, or update your IaC?"
7. Hand off to azure-validate for deep validation or azure-deploy for CI/CD setup

Track progress in upgrade-status.md inside the workspace root.

After upgrade is validated, hand off to:

• azure-validate — for thorough post-upgrade validation
• azure-deploy — if the user wants to set up CI/CD for the new app
