Vcenter appliance 5.5 to 6.5 problem

[ivanerben]

Hi all,

I'm trying to upgrade another vcenter appliance 5.5 Update 3f to 6.5 Update1. This one is failing in pre-checks, Only thing I'm able to find is in new appliance log /var/log/vmware/upgrade/upgrade-requirements.log

2017-10-18T12:58:25.773Z ERROR upgrade_commands Unable to execute pre-upgrade checks on host X.X.X.X
Traceback (most recent call last):
  File "/usr/lib/vmware/cis_upgrade_runner/bootstrap_scripts/upgrade_commands.py", line 2199, in execute
    preupgradeResult = self._executePreupgradeChecks()
  File "/usr/lib/vmware/cis_upgrade_runner/bootstrap_scripts/upgrade_commands.py", line 2693, in _executePreupgradeChecks
    ssoIps = preupgradeResult.get('extraArguments', {}).get('ur.appliance.sso.ipaddresses', {})
AttributeError: 'NoneType' object has no attribute 'get'

I have support case already open....

Solved by taking postgres db backup, deploying new vcsa 5.5, restoring postgres backup and then upgrade to 6.5
