Can you please tell me if anything different for upgrade for EV 10.0.4 to Ev 11.0.1 where EV archiving and DA located on one server?
My plan is upgrade EV archiving first and after follow DA upgrade process by stopping all services and upgrade any DA databases.
Is this right plan?
I suggest to do the other way around. First do DA, when that is ok, do EV.
The upgrade for DA is straightforward, and should not take long. The upgrade for EV can take a while, depending on your databases sizes.
Make sure to have good backups of the databases before starting!
