+description: Upgrade Backstage to the latest stable or specific version. Use when user says "upgrade backstage", "update backstage", "bump backstage", "backstage versions", or when the backstage.json version is behind the latest stable release.
+---
+
+# Backstage Upgrade Skill
+
+Use this skill when upgrading a Backstage monorepo to a newer version.
+
+## When to activate this skill
+
+- User asks to upgrade, update, or bump Backstage
+- `backstage.json` version is behind latest stable
+- User asks what version of Backstage is installed or available
+- User asks how to upgrade Backstage
+
+## Prerequisites
+
+### Environment
+
+- Yarn 4.1.1+ (check: `yarn --version`)
+- Node.js 20+ or 22+ (check: `node --version`)
+- Access to run `mise run` commands
+
+### Recommended
+
+- Backstage Yarn plugin installed (makes version management easier)
+- Clean git state (commit or stash changes before upgrading)
+
+## Upgrade Workflow
+
+### Step 1: Check current state
+
+```bash
+# Check installed version
+cat backstage.json
+
+# Check latest stable version
+yarn dlx @backstage/cli@latest --version 2>/dev/null || npx @backstage/cli@latest --version
+
+# Check outdated packages
+yarn outdated
+```
+
+### Step 2: Install the Backstage Yarn plugin (recommended)
+
+The plugin auto-manages `@backstage/*` versions based on `backstage.json`:
+
+```bash
+yarn plugin import https://versions.backstage.io/v1/tags/main/yarn-plugin
+```
+
+This creates/updates `.yarnrc.yml` and `.yarn/`. Commit these changes.
+
+### Step 3: Run versions bump
+
+```bash
+# Upgrade to latest stable
+yarn backstage-cli versions:bump
+
+# Or to a specific version
+yarn backstage-cli versions:bump --release 1.51.0
+
+# Or to the 'next' release line (weekly)
+yarn backstage-cli versions:bump --release next
+
+# Update custom plugins too (e.g., @roadiehq/*)
+yarn backstage-cli versions:bump --pattern '@{backstage,roadiehq}/*'
+```
+
+This updates `backstage.json` and migrates package.json deps to use `backstage:^` if the yarn plugin is installed.
+
+### Step 4: Pull in template changes
+
+The `create-app` template changes are NOT auto-applied. Check manually:
+
+```bash
+# View changelog
+yarn dlx @backstage/create-app@latest --version 2>/dev/null
+
+# Use upgrade helper for diff between versions
+open https://backstage.github.io/upgrade-helper/?yarnPlugin=0
+```
+
+Key files that often change in templates:
+- `packages/backend/src/index.ts`
+- `packages/app/src/App.tsx`
+- `packages/app/src/components/Root/Root.tsx`
+- `app-config.yaml`
+- `Dockerfile`
+
+### Step 5: Install updated dependencies
+
+```bash
+mise run install
+# Or: yarn install
+```
+
+### Step 6: Build and verify
+
+```bash
+mise run build:all
+mise run lint
+mise run test
+```
+
+### Step 7: Test locally
+
+```bash
+mise run dev
+```
+
+### Step 8: Commit
+
+```bash
+git add -A
+git commit -m "chore: upgrade backstage to $(cat backstage.json)"
+```
+
+## Key Files
+
+| File | Purpose |
+|------|---------|
+| `backstage.json` | Master Backstage version for the yarn plugin |
+| `.yarnrc.yml` | Yarn configuration (includes plugin if installed) |
+| `.yarn/plugins/` | Yarn plugin bundle |
+| `packages/app/` | Frontend React app |
+| `packages/backend/` | Node.js backend |
+| `plugins/` | Custom plugins (scoped `@internal/`) |
+
+## Troubleshooting
+
+### Package mismatches after upgrade
+
+```bash
+# Dedupe packages
+yarn dedupe
+yarn install
+```
+
+### Build failures
+
+```bash
+# Clean and rebuild
+mise run clean
+mise run install
+mise run build:all
+```
+
+### Lock file conflicts
+
+```bash
+rm yarn.lock
+mise run install
+```
+
+### Proxy issues (corporate networks)
+
+```bash
+export HTTP_PROXY=http://proxy.company.com:8080
+export HTTPS_PROXY=http://proxy.company.com:8080
+export NO_PROXY=localhost,internal.company.com
+export NODE_USE_ENV_PROXY=1
+export YARN_HTTP_PROXY=${HTTP_PROXY}
+export YARN_HTTPS_PROXY=${HTTPS_PROXY}
+```
