Hello,

I am having failover cluster ( 2 nodes ). I have updated both nodes few days back. Boht nodes are with same (latest) updates.

When I want to move/migrate virtual server between nodes, I will lose in 80% cases configuration. In 20% virtual servers are migrated. I was trying to do it also with turned off servers.

I was trying to search in logs, but there are nothing. 

Now I have to delete virtual server and recreate it again, configure IP, number of CPUs and RAM again. And this is really not good situation, when you need high availability.

All was working fine since last updates. I was also trying to go through these updates notes, but, there is no info about any changes in Hyperv.

I would like to ask you for help, or advice.
