# Sentry Upgrade Migration

Detect installed Sentry SDK versions, identify breaking API changes, apply automated codemods, and verify the upgrade succeeds with test events and traces.

## Current State

!`npm list 2>/dev/null | command grep @sentry || echo 'No npm Sentry packages found'`
!`pip show sentry-sdk 2>/dev/null | command grep -E '^(Name|Version)' || echo 'No Python sentry-sdk found'`
!`node --version 2>/dev/null || echo 'Node.js not available'`

## Overview

Sentry SDK upgrades require careful handling of breaking API changes. The v7 to v8 JavaScript migration is the most impactful, removing the Hub pattern, replacing Transaction/Span APIs with `startSpan()`, converting class-based integrations to functions, and requiring ESM-first initialization. Python SDK v1 to v2 similarly replaces `configure_scope()` with `get_current_scope()`. This skill automates version detection, runs the official `@sentry/migr8` codemod, applies manual fixes for patterns the codemod misses, and validates the upgrade with test events.
