Hi

I'm looking for a controlled way to migrate a SCCM 2007 server client to SCCM 2012. A push of SCCM Console is no option.
I 'll do all the testing but hoped to gain some time by having these questions answered:

*can an install of SCCM 2012 client be remotely triggered in one go (no uninstall of 2007 needed)?
*if uninstall is needed (of sccm 2007 client), does it need a reboot?

What command to use (preferrably powershell):

\\ourserver\Client\ccmsetup.exe" -argumentlist "SMSSITECODE=sitecode","SMSMP=oursccmserver","SMSCACHESIZE=8000","FSP=oursccmserver","CCMLOGMAXSIZE=104857600"

OR (guess that's the command SCCM is using)

Install-CMClient-DeviceName$ComputerName-IncludeDomainController$False-SiteCodePRD-ForceReinstall$True-AlwaysInstallClient$True-Verbose

Why not just create a package of the 2012 client and deploy it in your 2k7 en

Just run that command in a batch file then

Yes it will remove the 2007 client and then install 2012.

I preferr using Jason Sandys startup script, http://blog.configmgrftw.com/configmgr-client-startup-script/ it works great in migration scenarios as well. 

Create a gpo and add the script filter it on an AD group then you can still control which computers are migrated.. Works great.

Thanks! One more thing: do I need to import the machine in SCCM 2012 also or launching the SCCM 2012 install from a SCCM 2007 will do this?

This is the command I'm using now:

\\share\ccmsetup.exe /source:\\share\ccmsetup.exe /MP:sccmserver /forcereinstall SMSSITECODE:STG FSP CCMLOGMAXSIZE=...
