# Upgrading AlchemyCMS

This guide describes how to upgrade AlchemyCMS to a new version.

Upgrading Alchemy is mostly three steps.

  1. Update the gem
  2. Run the upgrade task
  3. Follow ups

# Update the gem

If you use Alchemy from a git branch, point it to the next stable release.

...
-gem 'alchemy_cms', github: 'AlchemyCMS/alchemy_cms', branch: '4.5-stable'
+gem 'alchemy_cms', github: 'AlchemyCMS/alchemy_cms', branch: '4.6-stable'
...

If you use Alchemy from rubygems, point it to the next stable release.

...
-gem 'alchemy_cms', '~> 4.5'
+gem 'alchemy_cms', '~> 4.6'
...

If you are using alchemy-devise for authentication, then update the gem as well. The major and minor versions of the alchemy_cms and the alchemy-devise gems match.

...
-gem 'alchemy_cms', '~> 4.5'
+gem 'alchemy_cms', '~> 4.6'
