What's the best way to migrate from SourceSafe to ClearCase?

Question

We currently have a fat SourceSafe DB with ten years of code in it. We\'re looking for an easy and stable way to import all of this in to a new Clearcase/Jazz environment.

From IBM's web site:

http://www-01.ibm.com/support/docview.wss?ratlid=cctocbody&rs=984&uid=swg21222507

and this:

However, ChrisF's answer is the same that I would suggest.

The effort involved generally is not worth it given the "benefit" of migrating the history.

I would just take snapshots of the current "tips" of the branches and put those under your new version control system.

I went through this exercise at least 3 times in my career. One conversion to Perforce and two to SVN.

I think I recall that we did some partial history imports, but then just dropped it all as the information we needed was in some other form. The actual repository history of changes just wasn't important enough to go through the pain. We did keep the database around for a year or so in case anyone wanted to look. I don't recall anyone complaining about it.

(I'm also curious why anyone would choose ClearCase over the rest of the ones out there - my guess is for integration with other Rational/IBM stuff)

EDIT

I would ask ClearCase/IBM. They'll have the best up to date information.
