Need to move pc from AD group to SEPM group

Hi

This is my scenario.

In SEPM (v12.1)

I have Group A, which is at top of the tree, and below it is groups of AD synched groups.

Then there is Group B, which is also on top of a tree, and below it are SEPM groups.

Not sure who has setup Group B, but there are some clients there.

I need to move a client from AD synched group, to a sub group under Group B.

How will i be able to achieve this?

One way i am thinking is to export the sylink from the group under GROUP B, then drop it to the client.

Would this move the client?

Thanks,

DM
