I)We are trying to move from server 2012 on our main poller and additional polling engines; all of which have an HA pool to Windows server 2016.
2)We have a QA environment. Based on my discussion with support, the method we need to follow is to rebuild the HA pools.

3)I was wondering if anyone has found an easier method. I would rather not have to disable all HA and truncate the HA tables as outlined in the KB. We were able to go through the process with support.

4)I'm going to test some other methods in QA. I would think this method would work:
a.Delete the main poller pool
b.Shut down the HA service on the main poller and main poller stanby
c.remove the associated table entries for the main poller standby that we are going to refresh.
d.repeat steps for the APE that we are going to refresh.
