We have 800+ clients that need to be changed from Users to Computers in SEPM. We are running SEP 11.07 and the MoveClient I am using is 3.0. After following the instructions and running the script, it fails at "get group structure metadata". Here is the log:

Are these groups, which contain the users you are trying to switch to computer mode, that are imported through AD?

Read throught PDF that comes with the moveclient utility.

You need to mention all the groups for which you want to move clients from Usermode to computer mode.
