I am trying to run a migration to SBS2011 in a ESXi 5.0 environment.
The SBS2003 I am migrating from is a VM on the same host.
I prepared the SBS2003 for migration and created the answerfile which is located on a physical USB-stick made available to the new VM.
After that I booted the new VM the DVD located in the host's drive, started the installation with choice of language, accepting the EULA, choosing the partition. The installation files were extracted and transferred. The VP rebooted, and hangs from there on on "finalizing installation" or whatever the exact wording in English might be (I am installing German language version).
It's the second time with a new answerfile that I have done this. The new VM is at 100% CPU load (it has one vitrual CPU). RAM usage is only 491MB out of the 12GB available to this VM.
