Should I check in my changes before I do rebase in clear tool

I use ClearCase for version control and have been working on few files in my child stream view.

Now I want to rebase to a baseline which has all the updates from other developers.

So, before I do the rebase, should I check in all my changes even though nobody has modified the files that I am working on?

It is preferable to do so, in order to avoid any mishap during the rebase.

But, another approach would be, assuming you are working in a snapshot (UCM) view, to:

• use a separate dynamic view (with the same config spec) to perform the rebase
• update the snapshot view (that should not touch the currently checked out files, especially if the rebase involves different files)
