Have the unfortunate task for migrating source code from Jazz SCM to GIT.   The optimal goal is to retain all the changeset history.     But attempts to walk though stream history changeset by changeset seems challenging as we encounter gaps due to dependencies... (as we accept changesets 1 by 1, hoping to create a corresponding GIT commit).    So wondering if conventional wisdom (for a successful outcome) is to instead map changeset "bundles" to git commits at the stream snapshot or baseline level.  I.e. accept all changeset for a baseline, do a git commit , tag this and move on to next one.  Appreciate any expert opinions or comments.
