Windows 2003 SP2 => 2008 R2 SP1 Upgrade 62% Rollback

Hello,

we have to upgrade our Windows Server 2003 SP2 x64 (DC), to Windows 2008 R2 SP1.
Unfortunately, a clean install is not an option.

The server is a virtual machine. Therefore, first we make a clone, for a test upgrade, of the server.

Adprep and domainprep was successful. Problematic Software: Acronis, DaemonTools, Kasperksy.. is uninstalled.

Will upgraded with a clean iso, downloaded from the VLSC.

All Windows 2003 updates have been installed and a clean-boot (msconfig : MS services, no startup items), was done.

During the upgrade, we download the installation updates (Get important updates for installation).

The environment variable MIG_UPGRADE_IGNORE_PLUGINS = IphlpsvcMigPlugin.dll was already tried in another upgrade.

We have the setupact.log (33MB) from the \$Windows folder.~ BT\Sources\Panther\ . But can't found the error.

The Upgrade stops at 62%:

Setup

Then the server reboots and performs a rollback :

Rollback
What can we do?

Regards,
Stefan

So I have questions:
1. Why is a clean install not an option?  Perhaps if I (we) understood why you feel it's not an option we could come up with an option you haven't thought about.
2. Have you tried upgrading to 2008 (non-R2) instead?

Try the upgrade without getting updates first.
Post the logs.

Hello Leew,

many many thanks for the great tip :-)

Upgrade number 8 with Windows 2008 SP1 without R2 was successful!

While the 2nd setup reboot, I got the error:

ErrorBut I fixed it with F8.

Could also the same problem with Win2008 R2 setup ?
Well no matter, it works!

I would give you 5000 points if I could ;)

Thank you
