Migrate Eclipse StatET to GitLab

We would like to migrate Eclipse StatET to GitLab.

We need to move:

• Issues from Bugzilla
• Git repositories from Gerrit
  At moment we have 7 git repositories. I think we should merge all repositories into one for GitLab.
  I already created such a merged git repository keeping the history and tags of all repositories. Shall I upload the git-bundle to this issue?
• Pages from MediaWiki
