Migrate from 8.8RC1 to New 9.4 Gitlab

Hello All,

Hoping to get a hand here . I am trying to create a new Ubuntu VM using the latest version of gitlab. However currently we have a Turnkey Linux Running 8.8RC1. Being that 8.8RC1 does not have an export function how should I go about getting the repos over? Can I simply copy over /home/git to the same location on the new server? Any advice on getting upgraded or exporting the projects would be much appreciated
