Description Yaniv Lavi (Dary) 2017-08-02 09:52:18 EDT
Description of problem:
We currently recommend a stepped upgrade from 3.5 to 3.6 for HE.
As we now support 3.6 NGN for upgrade flow and CLI is supported on this hypervisor, CEE would like to have a simpler upgrade method that will not require a stepped upgrade.
I suggest providing steps to copy existing answer file from RHEV-H el6 3.5 to next generation RHV-H el7 3.6 and change the answer to make the setup think it is an upgrade.

Can you provide steps for this? 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Upgrade RHV 3.5 to 3.6 with HE and RHEV-H/RHEL-H el6.

Actual results:
You need to step the HE cluster upgrade with RHEV-H 3.5 el7.

Expected results:
Reinstall to next generation RHV-H 3.6 el7 or RHEL-H 3.6 el7 directly and have steps to trigger upgrade of HE.

skipping 3.5 el6 -> 3.5 el7 -> 3.6 el7 ->3.6 el7 ngn 
going    3.5 el6 -> 3.6 el7 ngn

Just remember, the main reason for this 3.5 el7 -> 3.6 el7 was to trigger autoimport of HE SD, as per this solution:

Maybe we could ship an helper script or a set of ansible playbooks to make it even easier.

This helper script need to be updated in the KBase, but doesn't require a backport to 3.6.z codebase.

> This helper script for this process needs to be updated in the documentation and should be included in the 3.6.z code base.
