Folks , 

If my secondary site cross 5000 clients now I want to bypass those clients to direct primary site / any other secondary site within the hierarchy . 

What I Did ? 

I Uninstall the client and reinstall before that I added that machine IP Address range into targeted Boundary group but still it's going old MP only 

Anyone helps here ?

You just have to re-assign the clients to the new primary (no need to reinstall; there are scripts that can be used to assign a client to a new site). Then adjust boundary/groups. Done. 

SOrry , I adjust the boundary but no luck 

What do LocationServices.log and ClientLocation.log tell?

Locationservice log file getting old Management point only . 

Then you did not configure boundary/groups right or the site server has problems publishing to AD. 

Need to cross again
