Windows vCenter Server 6.0 upgrade to vCSA 6.5 Db Pre-Check Failed

This post was originally published on this site

Hi All,


I recently met a problem during inplace upgrade of Windows vCenter Server 6.0 to vCenter Server Appliance 6.5 – at the initial stage: database pre-check.

Right after Migration Assistant lunch and put in credentials of Administrator@vsphere.local and service account used by VC service, I get an error:

Upgrade Phase ‘vcdb:CollectRequirements’ failed. Exception: ‘NoneType’ object has no attribute ‘find’


I would appreciate any help and comments.
