Description (partial)

Upgrade HCMF from HCS 921 ( ) -> HCS 10.1.1 ( failed

Directly upgrade from HCS 921 ( ) -> HCS 10.1.1 (


This happens only in cases when the initially backed-up 9.2.1 vm was actually 'switched-back to 9.2.1  from an previously upgraded 10.x state' (using the admin cli command 'utils system switch-version').

So this is the scenario:  
1.	9.2.1 VM with some data(A switched-back vm from a previously upgraded 10.x state) 
2.	DRF Backup
3.	Fresh install 9.2.1
4.	DRF Restore (using backup done in step 2 above)
5.	Upgrade to 10.1  Results in failure
