# Downgrading from EE to CE
|
|
|
|
If you ever decide to downgrade your Enterprise Edition back to the Community
|
|
Edition, there are a few steps you need take before installing the CE package
|
|
on top of the current EE package, or, if you are in an installation from source,
|
|
before you change remotes and fetch the latest CE code.
|
|
|
|
## Disable Enterprise-only features
|
|
|
|
First thing to do is to disable the following features.
|
|
|
|
### Authentication mechanisms
|
|
|
|
Kerberos and Atlassian Crowd are only available on the Enterprise Edition, so
|
|
you should disable these mechanisms before downgrading and you should provide
|
|
alternative authentication methods to your users.
|
|
|
|
### Git Annex
|
|
|
|
Git Annex is also only available on the Enterprise Edition. 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 the Community Edition.
|
|
|
|
### Remove Jenkins CI Service entries from the database
|
|
|
|
The `JenkinsService` class is only available on the Enterprise Edition codebase,
|
|
so if you downgrade to the Community Edition, 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:
|
|
|
|
**Omnibus Installation**
|
|
|
|
```
|
|
$ sudo gitlab-rails runner "Service.where(type: 'JenkinsService').delete_all"
|
|
```
|
|
|
|
**Source Installation**
|
|
|
|
```
|
|
$ bundle exec rails runner "Service.where(type: 'JenkinsService').delete_all" production
|
|
```
|
|
|
|
## Downgrade to CE
|
|
|
|
After performing the above mentioned steps, you are now ready to downgrade your
|
|
GitLab installation to the Community Edition.
|
|
|
|
**Omnibus Installation**
|
|
|
|
To downgrade an Omnibus installation, it is sufficient to install the Community
|
|
Edition package on top of the currently installed one. You can do this manually,
|
|
by directly [downloading the package](https://packages.gitlab.com/gitlab/gitlab-ce)
|
|
you need, or by adding our CE package repository and following the
|
|
[CE installation instructions](https://about.gitlab.com/downloads/).
|
|
|
|
**Source Installation**
|
|
|
|
To downgrade a source installation, you need to replace the current remote of
|
|
your GitLab installation with the Community Edition's remote, fetch the latest
|
|
changes, and checkout the latest stable branch:
|
|
|
|
```
|
|
$ git remote set-url origin git@gitlab.com:gitlab-org/gitlab-ce.git
|
|
$ git fetch --all
|
|
$ git checkout 8-x-stable
|
|
```
|
|
|
|
Remember to follow the correct [update guides](../update/README.md) to make
|
|
sure all dependencies are up to date.
