ClearCase to Git migration

Question

We are working on converting our CC Vobs to GIT we have both base and UCM vobs, I have seen many topic with no clear steps.

Is there any tool or steps that can keep history and branches?

Answer 1

No, there is no ClearCase to Git bridge, convertor or adaptor that I know of (retaining the full history, with all its events).

It is best to:

• restrict a git repo to an UCM component (while a Vob can contain multiple component and be way too big for a Git repo to handle)
• add in a git repo only the last few baselines of a given components (see "Equivalent of the clearcase baseline and clearcase activities in Git?")
• keep ClearCase in read-only mode for history archive.

You will find a similar advice in:

• "Save history from Clearcase to Git?"
• "Sync GIT and ClearCase"

You can try:

• a more elaborate method in "How to bridge git to ClearCase?"
• the git-cc project (might be obsolete by now)
