We are running IA 8.1.10, have a pair of redundant gateways and a pair of remote Ignition servers acting as IO servers. We also have the EAM module. Would like to upgrade from 8.1.10 to 8.1.17. Last time we upgraded, we ran into unexpected issues. So… questions:
- Should the main or remote pair be upgraded first? curiously not found in the best practices write up.
- Why is it recommended to upgrade to .17 from .0 or .1 but upgrade to .20 if running 7.9 ?
