I have a repo mirror server (myrepo) that was originally created to mirror and sync with a remote (repoA). That is, I used something like the following to create it.
cd myrepo
repo init -u git://repoA-server/manifest.git --mirror
repo sync
...then I modified manifest file's fetch line to use myrepo server so users can clone from myrepo mirror
So now repoA is gone and doesn't exist anymore. It has been replaced with a new repoB server at a different URL which has modified some of the branches and uses a new manifest file for those branches.
How can I resync my myrepo mirror with this new repoB? I don't want to blow away my myrepo and just create a new mirror. I want to retain its history and just update some of the branches to now track from repoB, and use the new manifest file (which I will again modify to fetch projects from myrepo).
I'm not sure how to go about doing this? I'm wondering if I can simply make some change in myrepo and then just run 'repo sync' to have it sync up with new mirror (i.e. do a fetch/merge for updates branches)? Or do I have to clone myrepo then do something like add repoB as a remote, create tracking branches, fetch/merge myself, and try to push that up to myrepo?
