We are looking at upgrading our environment to add in HA paris for every poller and AWS system.
It became obvious to me that we don't actually know how a update activity with HA would work, or what it would look like.
I get how the HA functions with unplanned service outages, but here is what i'm confused on:
- Are we able to update the offline B set, then switch to the A set and preform the upgrade there?
- How would that work with a Database? Wouldn't there be a period of mismatch between the DB and the Pollers?
Any pointers to documentation or better yet examples would be greatly appreciated, and Anyones hands on experience would be just Fantastic.
Thanks all
