Hello. I tried reading through all the comments first, so apologies if this was addressed, but if you are using hybrid and have migrated 100% of the mailboxes, you have decommissioned all servers except for 1, but powered it off to leave attributes in AD, and you have a single Windows 2019 server that has management tools installed with the latest exchange 2019 CU14; does that then need to move to SE for management tools, in order to avoid landing on the out of date report?
I am currently working towards getting to this as the end goal, but if going to CU14 on the management tools will eventually flag me as out of date and throttle me, I'd like to know before next year. I already hit a stage 5 throttle once, don't intend to see it again.
Thank you in advance.
