How to migrate from bitbucket to stash

[David Kunkel]

We are currently using BitBucket and want to move our repositories to Stash.

It documented on Atlassian Docs:

It is significat to make Bare clone, not simple Copy clone. Because if you make not a Bare mirror, you get no remote branches. And push --all will not work fine.

I used follow commands to completelly migrate from one Git to another, this will copy anything:

git clone --bare git@bitbucket.org:/login/myrepo.git
cd myrepo.git
git push --mirror git@stash.acme.com:/project/myrepo.git
cd ..
rm -rf myrepo.git

In this solution you no need to add remote.

Thanks Alexey. You're quite right - that's actually a better way to do it.

Wouldn't it be better to mirror the clone at the first step?

git clone --mirror git@bitbucket.org:/login/myrepo.git

Also, is the process repeatable if commits are made to the Bitbucket repo?

Here is a python script to do this for you.

Hi David,

I guess this depends on how many repositories you have to migrate? If we're talking 5-10, then frankly I would just do it manually for now.

If you have more thant that it might be worth thinking about writing a script (which we could definitely help with). You could use both the REST endpoints to query the Bitbucket repositories and re-create them in Stash.

Cheers,

Not specifically. It's really just the normal Stash documentation you might want to take a look at:

https://confluence.atlassian.com/display/STASH/Stash+Documentation+Home

For each repository in Bitbucket you will want to clone the repository to a machine, create a matching repository in Stash and then push all the branches/tags. Something like:

git clone git@bitbucket.org:project/repo-name.git
cd repo-name
git remote add stash ssh://git@server:7999/PROJECT/repo-name.git
git push --all stash && git push --tags stash 

You may then also want/need to setup user permissions on your projects as appropriate to your organization.

I hope this helps?

Hi Charles,

Is there some documentation somewhere on how to do this manually?

Thanks,

Thanks for everyone's help - I'll get started with the migration today.
