Migrate clients from ConfigMgr2012R2 to Current Branch

[surfincow]

Hello,

 

We are moving from 2012R2 to CB and I'd like to verify the following in regards to migrating the clients over to the new system.

 

We have 2 boundary groups configured for the geographical location of the clients which may cause a problem as the groups will overlap and there isn't really a way so segregate them out. The old system is published in AD and the new one is not.

 

The biggest divide in our clients regarding migration are workstations and servers. We plan to do workstations first, then servers. Currently both wks and server OU's have GPO's configured for install and site assignments.

 

 

We have the following GPO's configured on our wks and server OU's

 

-Configure ConfigMgr 2012 Client Deloyment Settings (ccmsetup.exe install parameters to r2 site)
-Configure ConfigMgr 2012 Site Assignment = r2 site
-Specify intranet MS update service location = r2 sites WSUS

 

I will assume this takes precedence over what is published in AD so if that is correct, publishing the new site so both are listed in AD will not cause a problem?

 

 

When we go to migrate our clients, we can change the GPO settings on the respective OU's to::

 

-Configure ConfigMgr 2012 Client Deloyment Settings (ccmsetup.exe install parameters to cb site)
-Configure ConfigMgr 2012 Site Assignment = cb site
-Specify intranet MS update service location = cb sites WSUS

 

and let the clients grab the new sccm client from WSUS (where it is published) and it will upgrade and move over to the new system.

 

Once we have all the clients migrated, unpublish the r2 site from AD and modify the GPO's as follows:

 

Configure ConfigMgr 2012 Client Deloyment Settings = remove
Configure ConfigMgr 2012 Site Assignment = remove
Specify intranet MS update service location = cb sites WSUS

 

any new installs going forward will just grab the install information from AD.

 

 

 

Does this seem logical?

If you're not using the boundaries for automatic site assignment, there shouldn't be a problem with overlapping boundaries.

So for the time being the GPO's are handling the site assignments so what is published in AD does not matter as long as we have the GPO's in place. Correct?

[Peter van der Woude]

Correct and if you're not sure you can fairly easy test the behavior.
