Upgrade VMM 2008 R2 SP1 RC to VMM 2008 R2 SP1


Just saw one of my lab machine is running VMM 2008 R2 SP1 RC version. Therefore i plan to to try the upgrade process and see if it is working since MS Connect site publish this tool.To get it, click here

Note: Upgrade process always has a risk and it may not 100% working. But for me, it is no harm for me to try it since it is a lab environment. :)

1. As usual, I'm a pre-caution guy. Always perform backup in case i want to roll back. Here i use VMM Console to perform backup of the database

2. Uninstall VMM 2008 R2 RC components with Retain database. During uninstall process, i received an error message saying the VMM Manager is running. Therefore , i stop the VMM Manager services and uninstallation process continue. Once complete, i restart the server.

3.After boot up, i open command prompt with elevated privileges and execute this command.

UpgradeVMMR2SP1RC.exe –server servername

–database VirtualManagerDB


Note: During execution of this command, it does not work. I use the server name from SQL Management Studio- small capital. Weird, but it is working.

4. Go to registry and manual delete VMMService which located in

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services

5. Reboot the system.

6. Reinstall all VMM components

For me, Upgrade process is quite smooth with some obstacles but still  manageable. With the upgrade process complete, there is no more time bomb appear on the console. Your upgraded VMM will indicated with this version:-


Good luck !
