I have a single node GitLab with latest community edition version and took a backup from it.
I have created a Gitaly Cluster with the following architecture: -
- Gitlab Server for the users to access
- Praefect Server
- 3x Gitaly servers that are being controlled by the praefect server
- PostgreSQL server for Praefect Database
The GitLab Cluster nodes are all running on the latest community version same as the single node version.
I have tried to restore the single node backup to the GitLab cluster but it give me the following error :-
[root@gitlab-server ~]# gitlab-backup restore 1613532569_2021_02_17_13.8.4_gitlab_backup.tar Non tarred backup found in /var/opt/gitlab/backups, using that GitLab version mismatch: Your current GitLab version (13.8.4) differs from the GitLab version in the backup! Please switch to the following version and try again: version: 13.7.1 Hint: git checkout v13.7.1
I searched for any method of migration and couldn’t find any.
Could anyone help me please?
