Move folders while stuff checked out?

[erict]

Is it ok to move a bunch of folders, even though some users have files checked out? Specifically, we want to add a new trunk and move all our current top-level projects into this new trunk. I'm assuming I can't just grab the root and move everything into project which is part of the root selection... That would be kinda recursive.
So I'm planning to take each of our existing 1st-level projects and move them into a new 1st-level project. Will any checked-out files be able to check-in, after the working directory is fixed up? Or does every project need to be re-bound (binded?)?

Thanks for some clues on how to do this the best way.

A move operation will fail if files are checked out in the folder you're trying to move.

The best bet is to checkin files in the affected folders, unbind the project from SourceControl, do your moves and rebind.
