Subject: What to do if the path of my git submodules change upstream
Message-ID: <000301cca46d$5428c3d0$fc7a4b70$@heigl-online.at>

Hi everyone!

First setup of my git was a server (with ssh) and some clients.

Today I changed to gitolite because I wanted a more sophisticated way of
managing my repos. So far so good…
So the old path “ssh://[ip]/[fullpath].git” would change to a new path
“git@[servername]:[gitreponame]”. 
This is no problem for “normal” repos, I change the remote origin and
continue using push and pull.

I have some submodules:
I changed the .gitmodules to reflect my changes, did a git submodule sync.
This works flawlessly too!

But what if someone wants to checkout an older version of the project? (for
comparison, or because he/she wanted to try something out)
He would get an old .gitmodules with old paths.
After a git submodule sync he would get errors, because old paths won’t work
anymore, because I changed some paths on the server 

It is only one project I have this problem and therein I changed the
.gitmodules only 3 times. Is it possible to rewrite .gitmodules on these
specific  commits on the server (perhaps with git-filter-branch)?
Or is there another easy solution? Has someone ever had this problem?

Hope you can help,
Kind regards,
Harald Heigl
