SCCM client re-assign

Question

Hi,
We have two primary SCCM 2007 sites managing over 7K clients. for one of primary server performance issue, we want all clients to be managed by single primary site.
By moving boundaries from ABC to XYZ site, do you think that client will assign to XYZ site automatically? or we have to manually assign clients from ABC to XYZ site?
Note:
- Client push not enabled.                                                                                                                                                
- Active directory schema extended.
Thanks in advance....!

No they won't. Client's never automatically reassign themselves to a different primary site.
Are the sites in the same hierarchy? If so, then you can send a script to them to assign them:

If they are not in the same hierarchy, your only supported choice is to deploy the agent again:
