Hello,



I am currently trying to migration from 2012r2 SP1 to 1702 - both are stand alone primary sites. I have the new site setup on new hardware with a new site code in parallel. Both source and destination sites have been extended to AD. Both sites have the same boundary groups and use boundary groups for site assignment based on AD sites. All objects have been migrated over from source to destination site.



Now I would like to test migrating the sccm clients over - the issue i'm running into it is that if I manually change the site code on a test machine to point to the new site - after a period of time (<24hrs) it reverts back to the old site. The LocationServices Log shown below is from the time it was at the new site till it reverted back to the old site.

My guess is this is due to the both sites publishing to AD via boundary groups. According to other threads I have read and Microsoft articles, auto-assignment through doesn't work if a site is already assigned. This doesn't appear to be the case based on my scenario. How insight as to how I can change the site code on a test machines without it reverting back to the old.

I'm sure I might have missed some information so please let me know and I can share.



Thanks
