We are in the midst of a migration from SBS 2003 to SBS 2011. The Migration Preparation Tool when run on the SBS 2003 box completes the forest upgrade, schema upgrade, licensing, configure exchange for migration, etc... but FAILS on the MBCA scan and will not continue.
The problem in the log states that "Required registry access is not allowed
" from the BPAEngine. When trying to run the MBCA on its own, it gives the same error in an alert box and cannot procede.
What has been done so far...
- ALL prerequisites have been installed (Powershell 2.0, MBCA, etc.)
- SBS 2003 is completely up to date with service packs and windows updates
- Remote Registry and WS-Management services are started
- This is NOT
the prerequisite problem described here http://support.microsoft.com/kb/2542156
Help is much appreciated...we are dead in the water at this point. No KB articles appear to be found that match this exactly.
