We currently run our own Git server but we are seriously considering moving all our repos to Bitbucket. We have 300+ bare repos and we're wondering if there's a way to quickly migrate these over? Really we just need the code and all branches and tags but we don't want to spend hours doing it manually.
I think that your best bet would be to write a script to do this. You would create the repositories using the REST api: https://confluence.atlassian.com/display/BITBUCKET/repository+Resource#repositoryResource-POSTanewrepository and then push the data into them using git
Edit: I also found the following
curl --request POST --user username:password https://api.bitbucket.org/1.0/repositories --data name=myrepo --data scm=git
