How can I downgrade my version of gitlab?

I’m running GitLab version (8.8.1-ee) and need to downgrade to version: 8.3.2
Can’t find any clear instructions/documentatuion to do this, can anybody help or point me
in the right direction ?

If you have a source installation, you will simply need to stop gitlab, and checkout to the version your want to go to.

If you are using an omnibus installation, this guide should be helpful:
