Migrating to BitBucket from Subversion
Join the DZone community and get the full member experience.
Join For FreeI've recently started the process of moving all of my Subversion repositories to BitBucket. BitBucket is my preferred git hosting supplier as its pricing structure suits me much better; that is, I have lots of private repositories and GitHub is too expensive for my case!
As I needed to migrate over one hundred repositories from Subversion to BitBucket, I automated it via a simple shell script. Rather usefully, BitBucket has an API that let me create the repository using curl and then use git to do the rest.
I've put this script here in the hope that it may be useful to someone else. It's certainly been useful to me!

Note that at the top there's this section:

ou need to put your information here if you want to use this script :)
The authors.txt file is a simple text file that maps Subversion user names to git names and emails. It should look something like this:
rob = Rob Allen <rob@akrabat.com> jsmith = John Smith <jsmith@example.com>
To use this script, I simply call:
svn2bitbucket.sh reponameand it does its thing. Note that it's not especially fast for a repository that has lots of history. You can also do svn2bitbucket.sh reponame 1 which will delete the repository on BitBucket first which allows you to re
