# ClickHouse Upgrade & Migration
## Overview
Safely upgrade ClickHouse server and the `@clickhouse/client` Node.js SDK, with
rollback procedures and breaking-change detection. The workflow is check versions
→ review changelogs → upgrade the client → upgrade the server → validate →
rollback if needed. Full command sequences live in
[references/implementation.md](references/implementation.md); the runnable
migration, validation, and rollback code lives in
[references/examples.md](references/examples.md).
## Prerequisites
- Current ClickHouse version known (`SELECT version()`)
