If you ever decide to downgrade your GitSwarm EE back to GitSwarm, there are a few steps you need take before installing the GitSwarm package on top of the GitSwarm EE package, or, if you are in an installation from source, before you change remotes and fetch the latest GitSwarm code.
First thing to do is to disable the following features.
Kerberos and Atlassian Crowd are only available for GitSwarm EE, so you should disable these mechanisms before downgrading and you should provide alternative authentication methods to your users.
Git Annex is also only available for GitSwarm EE. This means that if you have repositories that use Git Annex to store large files, these files will no longer be easily available via Git. You should consider migrating these repositories to use Git LFS before downgrading to GitSwarm.
The JenkinsService class is only available for GitSwarm EE, so if you downgrade to GitSwarm, you'll come across the following error:
Completed 500 Internal Server Error in 497ms (ActiveRecord: 32.2ms)
ActionView::Template::Error (The single-table inheritance mechanism failed to locate the subclass: 'JenkinsService'. This
error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this
column if you didn't intend it to be used for storing the inheritance class or overwrite Service.inheritance_column to
use another column for that information.)All services are created automatically for every project you have, so in order to avoid getting this error, you need to remove all instances of the JenkinsService from your database:
Package Installations
sudo gitswarm-rails runner "Service.where(type: ['JenkinsService', 'JenkinsDeprecatedService']).delete_all" Source Installations
bundle exec rails runner "Service.where(type: ['JenkinsService', 'JenkinsDeprecatedService']).delete_all" productionAfter performing the above mentioned steps, you are now ready to downgrade your GitSwarm EE installation to GitSwarm.
Package Installations
To downgrade a package installation, it is sufficient to install the GitSwarm package on top of the currently installed one. You can do this manually,
Source Installations
To downgrade a source installation, you need to replace the current remote of your GitSwarm EE installation with the GitSwarm remote, fetch the latest changes, and checkout the latest stable branch:
git remote set-url origin git@gitlab.com:perforce/gitlab-ce.git
git fetch --all
git checkout releaseRemember to follow the correct update guides to make sure all dependencies are up to date.
