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?

Solution

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)
