Migrate from Gitlab 6.5.1 to 7.13.5


I’m trying to migrate my old bitnami gitlab server V-6.5.1 to a new server installed from source V-7.13.5 and i’m facing issues while trying to import db and repositories.

The new server V-7.13.5 has been installed with mysql to keep db compatibility with the bitnami server, and is up and running, next step is to import the mysql db and the repositories.

I’ve copied the repositories, inject the db in mysql and follow the instructions found here http://mrickert.com/2013/09/24/gitlab-server-migration/ (Thanks Michael !) but i’ve got many issues at the last step : bundle exec rake gitlab:check RAILS_ENV=production

Some of the issues are now resolved but it remains problems with sidekiq and the rake migrate which try to create tables already existing.

If someone has successfully done this kind of migration and can help me, it would be great !
Thanks in advance,
