Recommendation on Tools to migrate from Clearcase to SVN?

clearcasemigrationsvn

I'm on the lookout for tools to migrate from ClearCase to SVN.

Ideally would like to get all history information, or as much as can be acquired.

Incremental merges would be very beneficial but isn't required.

Best Solution

This looks about the best. Polarion's business is SVN, so I guess they have a vested interest in making as many people as possible use it...

Oh, back up all your data before hand, do it on a test repository first, etc, etc.
