I'm currently running a gitlab 6, which I've installed locally. Now I'm trying to migrate my services to docker. Luckily there is a gitlab docker container, but it is version 8 and provides the tree volumes /etc/gitlab, /var/log/gitlab and /var/opt/gitlab. But I only have gitlab files in /home/git/.
Is there any way of migrating a gitlab 6 to version 8 in a docker?
I know this question is somehow related to How to migrate gitlab backups to new server which has latest gitlab version but this is only within a major release.
