# Migrate GitLab CI to GitLab CE or EE
This document was moved to [another location](https://docs.gitlab.com/).
Beginning with version 8.0 of GitLab Community Edition (CE) and Enterprise
Edition (EE), GitLab CI is no longer its own application, but is instead built
into the CE and EE applications.
This guide details the process of migrating your CI installation and data
into your GitLab CE or EE installation. **You can only migrate CI data from
GitLab CI 8.0 to GitLab 8.0; migrating between other versions (e.g.7.14 to 8.1)
is not possible.**
We recommend that you read through the entire migration process in this
document before beginning.
## Overview
In this document we assume you have a GitLab server and a GitLab CI server. It
does not matter if these are the same machine.
The migration consists of three parts: updating GitLab and GitLab CI, moving
data, and redirecting traffic.
Please note that CI builds triggered on your GitLab server in the time between
updating to 8.0 and finishing the migration are lost. Your GitLab server
can be online for most of the procedure; the only GitLab downtime (if any) is
during the upgrade to 8.0. Your CI service remains offline from the moment you
upgrade to 8.0 until you finish the migration procedure.
## Before upgrading
If you have GitLab CI installed using Omnibus GitLab packages but **you don't want to migrate your existing data**:
