SCVMM 2012 RC to RTM upgrade fails with error “upgrading from currently version is not supported”

 

I  have just tried to upgrade SCVMM 2012 RC to RTM and it failed to upgrade with following error “Upgrading from the currently installed version of VMM System Center 2012 Virtual Machine Manager is not supported. You must be running VMM 2008 R2 with Service Pack 1 (SP1) to upgrade to System Center 2012 Virtual Machine Manager.”

·         Uninstall current (RC) version of SCVMM. Make sure you select “Retain Database” in Database Options.

·         Using SQL Server Management Studio modify values of “DatabaseVersion” and “QFEDatabaseVersion” in table  tbl_VMM_GlobalSetting from RC (3.0.5007.0) to RTM (3.0.6005.0 or alternatively match to the version of setup.exe).

 

• Start SCVMM 2012 installation and select existing database.
• Finally, Don’t forget to update the VMM host agents!!

P2V using SCVMM error's at select host screen because of disk space requirement

Have you ever seen below error while converting P2V using SCVMM?

There is not enough disk space on the available volumes.

Maximum disk space on the most appropriate volume, accounting for the host resource utilization  (in megabytes): 60766

The virtual machine requirement (in megabytes): 162836

The maximum available space at the time of evaluation, after considering the virtual machine requirements (in megabytes): 139290

ID: 3501

I was bit worried after seeing error because currently I am having cluster server with more than 10 gigs of free space and it’s always fine while creating new VM. You don’t need to worry about above error because it simple to convert P2V if you are definitely sure about free space on host. Go to below screen and press next after selecting system drive only.

After selecting above continue with wizard by pressing next till you reach last second tab \ option in wizard “Conversation option”. Once you are there go back to above screen and select all drives that you want to be in virtualised machine and then press “Conversion Information” in the left side of the wizard and finally create to finish wizard. That’s all you have to do if you get above error while converting Physical to Virtual using SCVMM or Microsoft System Centre Virtual Machine Manager 2012.
