Solution 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)
