Error Uninstalling VMM 2012 SP1

With the release of System Centre 2012 R2 it was time to upgrade our production deployment of VMM.

This is installed on a single Windows 2012 Standard Edition server.

The plan was to uninstall VMM and the console and upgrade the OS to Windows 2012 R2.

I immediately hit a issue where VMM would not uninstall using add and remove programs.

I was presented with a pop up error message saying:

“you cannot upgrade from the currently installed version of VMM to system center 2012 SP1 virtual machine manager. You must first uninstall VMM,  and then install SCVMM 2012 SP1. If you are running system center suite, when you uninstall VMM, you can retain the database. When you install System center 2012 SP1, use the retained database”

Solution:

Using the Following TechNet Article as a reference use the command line to uninstall the VMM Server and Console:

The VMServerUninstall.ini file was modified as below:

NOTE: The below Deleted the VMM Database, make sure you take a backup!

[OPTIONS]
# RemoteDatabaseImpersonation=1
# RetainSqlDatabase=1
# ForceHAVMMUninstall=1

 

The command I ran from and administrative command prompt was:

setup.exe /server /x /f c:\temp\VMServerUninstall.ini /SqlDBAdminDomain "DOMAIN" /SqlDBAdminName "USERNAME" /SqlDBAdminPassword "PASSWORD"

 

setup.exe /client /x

The result, VMM 2012 SP1 uninstalled, I am now moving on to upgrading the OS to Windows 2012 R2 and re-installing VMM Server

    Hello

    Your file contain no options as the # mean it’s a comment.
    the RetainSqlDatabase=1 should prevent the deletion.
