azure-upgrade

Moves an app already running on Azure onto a newer hosting plan or service and checks it still works afterwards; it can also update old Microsoft code libraries inside Java projects.

WHEN TO USE

SCOPE

USE FOR

Upgrade a Function App from Consumption to Flex Consumption.
Migrate an App Service workload to Azure Container Apps.
Migrate Azure Cache for Redis, including its Enterprise tier, to Azure Managed Redis.
Modernize legacy Java code from com.microsoft.azure to the modern com.azure SDK.

NOT FOR

Migrating a workload from another cloud provider; use azure-cloud-migrate for that.

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 Java com.microsoft.azure.* → modern com.azure.*). 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"
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"
Migrate Azure Cache for Redis (ACR/OSS) to Azure Managed Redis (AMR)	"Migrate my Redis cache to AMR", "ACR to AMR", "OSS to AMR", "Upgrade my Premium P2 cache to Managed Redis", "Pick an AMR SKU", "Convert my Redis IaC template to AMR"
Migrate Azure Cache for Redis Enterprise (ACRE) to Azure Managed Redis (AMR)	"Migrate my Enterprise_E10 cache to AMR", "ACRE to AMR", "Update my ACRE IaC template for AMR", "Migrate EnterpriseFlash to AMR", "Migrate my geo-replicated Enterprise Redis"

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_bestpractices and mcp_azure_mcp_documentation MCP 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
Azure Cache for Redis (ACR/OSS) Basic/Standard/Premium	Azure Managed Redis (AMR)	services/redis/redis-to-amr.md
Azure Cache for Redis Enterprise (ACRE) / Enterprise Flash	Azure Managed Redis (AMR)	services/redis/redis-to-amr.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.

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

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-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

This skill ships inside the Azure Skills Plugin. Listed package contents include hooks and an MCP server. Installed components and skill versions may vary by AI tool.

Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.

Install checklist

Check selected tools if a picker appears; Claude Code may be unchecked under Additional agents. ↑/↓ moves, Space toggles selections, Enter confirms.
Without a tool picker, check Installing to: for your intended tool. Stop if it names a different tool.
If asked, choose Symlink (Recommended) for shared files or Copy to all agents for separate copies; review the summary before confirming installation.
Install the find-skills skill? defaults to Yes, adding another skill for all projects. Choose No if you don't want that extra installation.

Skills CLI 1.7.2 sends install data to skills.sh by default, including the source, skill names, target tools and file details; GitHub sources are reported only when GitHub confirms the repository is public, while other remote sources can also be reported. Confirmed-public GitHub sources also trigger a security-audit request. Before installing, set the environment variable DO_NOT_TRACK=1 or DISABLE_TELEMETRY=1 to disable both.

npx skills add microsoft/azure-skills --skill "azure-upgrade" --full-depth

After installing for Claude Code, open it in the installation project if you chose Project; Global makes the skill available across projects on this computer. Once Claude Code loads the skill, its description helps Claude decide when to use it.

If installation created a top-level skills folder that did not exist when your Claude Code session started, run /reload-skills in that session. Run it again after later changes in that folder.
