公司老的服務(wù)器即將到期，且不準(zhǔn)備續(xù)期(打算在公司賬號下新買ECS服務(wù)器，舊的服務(wù)器是在個人賬號下購買的),舊服務(wù)器上的gitlab服務(wù)需要遷移到新的服務(wù)器上坎匿。
由于Gitlab自身的兼容性問題待侵，高版本的Gitlab無法恢復(fù)低版本gitlab備份的數(shù)據(jù)胶滋。要么新服務(wù)器安裝和舊服務(wù)器一樣版本的gitlab,部署好環(huán)境后開始備份和數(shù)據(jù)遷移;要么舊服務(wù)器上的gitlab按步驟升級到最新版本后再備份，新服務(wù)器上直接安裝最新版本皆的，并恢復(fù)對應(yīng)版本的數(shù)據(jù)覆履。
強(qiáng)迫癥用戶肯定選擇升級到最新版啊。gitlab的版本升級也比較個性费薄，下邊請看我慢慢道來：
安全起見硝全，舊服務(wù)器升級Gitlab前，建議先備份數(shù)據(jù)(雖然是老版本的楞抡，但總比丟失了的好)伟众。
查詢版本及備份
查看gitlab版本(二選一):
cat /opt/gitlab/embedded/service/gitlab-rails/VERSION
gitlab-rake gitlab:env:info
備份10.3.3版本數(shù)據(jù)
gitlab-rake gitlab:backup:create RAILS_ENV=production
備份后的文件一般是位于/var/opt/gitlab/backups下, 自動生成文件名文件名如1541739348_2018_11_09_10.3.3_gitlab_backup.tar
升級路線 10.3.3 ---> 10.8.7 ---> 11.4.5 (10.8.7是版本10中的最后一個版本)
創(chuàng)建升級所需文件 touch /etc/gitlab/skip-auto-migrations
yum install gitlab-ce

舊服務(wù)器上安裝的gitlab版本是10.3.3，最新的gitlab版本是11.4.5召廷，要從10.版本升級到11.版本需要先升級到10.*的最后一個版本官方是這么規(guī)定的凳厢。
yum install gitlab-ce-10.8.7

升級到10.8.7后重新初始化一下配置并重啟gitlab
gitlab-ctl reconfigure
gitlab-ctl restart
訪問重啟后的gitlab,查看是否成功；繼而升到最新版本(11.4.5)
yum install gitlab-ce

Deprecations:
== Prometheus ==
Detected Prometheus version 1.x. Version 1.x has been deprecated and support will be removed in GitLab version 12.0.
To upgrade to Promtheus 2.x, use `gitlab-ctl prometheus-upgrade` command.
Running this command will migrate all your existing data to format supported by Prometheus 2.x.
This can be a time consuming operation. To skip migrating the data, and instead remove and start fresh, run `gitlab-ctl prometheus-upgrade --skip-data-migration`.
Check https://docs.gitlab.com/omnibus/update/gitlab_11_changes.html#11-4 for details.

按照給出的信息升級gitlab-ctl prometheus-upgrade并重啟gitlab-ctl restart,應(yīng)該就可正常訪問11.4.5版本的gitlab了竞慢。

注意：這里沒有后面的_gitlab_backup.tar名字
一路yes筹煮，恢復(fù)是會先刪除新服務(wù)器上所有g(shù)itlab數(shù)據(jù)的遮精。
恢復(fù)完數(shù)據(jù)后gitlab-ctl restart重啟，即可正常訪問到原有的gitlab數(shù)據(jù)了
