thank you!I just wanted to check if there is any difference between a copy that was taken freezing teamsite, and a copy that was taken with teamsite stopped. but i think you confirmed that they are both the same.
if you have a backup of the store taken after running iwfreeze, that should be no different than the store when the server is stopped - except for the TSRunning file as indicated in the previous post.
You should be able to run iwmigrate on the backup copy. Of course, remember that any changes since that backup will have to be moved over as well unless you don't care about those changes..
