No clear way to update my gitlab from 6.9.2 to 7.X/8.X?
My issue I am working on at least a week:
I have a running productive GitLab-Server Version 6.9.2. Its installed without omnibus and it uses a mariadb on a Linux mashine.
I want to upgrade this Server to the newest Version 7.X/8.X (whatever). Sounds simple, but I work on this problem for a week now.
Main Question: How do I update my gitlab from 6.9.2 to 7.X/8.X?
I tried many ways to do so. Important: I installed a new (latest version) empty GitLab Server with omnibus on a virtual mashine to test those ways, so the most investigation goes to look up how to import the data to the latest version. No, I dont want to update the running version of my gitlab server. No, I dont have at present the opportunity to clone my running live GitLab Server:
Way 1 The more stupid way:
- made a dump of the MariaDB
- convert it with mysql-postgresql-converter suggested from gitlab
- tried to import it into postgres
Failed
Failed because its a different database schema from 6.X to 7.X/8.X (summary of the error messages)
Way 2 Backup and Restore:
- followed this instructions:
https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/mysql_to_postgresql.md
- i tried to restore the backup in the new GitLab
Failed
My GitLab-Server told me, that the database schema in the backup is too old for this version (8.0.3). Backup aborted
Way 3 Backup and Restore but with an identical mashine:
- I deleted my VM with the latest GitLab-Version and tried to install a GitLab-Version which is the same as the one I want to export from (6.9.2)
- Did the same steps like Way 2
- tried to import and then to upgrade the identical mashine to the newest
- copy the backup file into the right folder
- run
gitlab-ce run rake gitlab:backup:restore RAILS_ENV=production BACKUP=1443512522 --trace
Failed
Got this:
gitlab-ce run rake gitlab:backup:restore RAILS_ENV=production BACKUP=1443512522 --trace

Now I am clueless what I basically do wrong. There has to be a way to import that data from the live GitLab to the latest version of Gitlab. I appreaciate every help I can get.
