Goodbye, Exchange 2010 (And advice moving forward)
The end of an era. Exchange 2010 is End of Life today–no more security updates, no more extended support. I know there are quite a few servers left out there in the world, but many of them are not even in use (or they were merely in place for hybrid purposes). If this is you (or your customers), then make sure you get this taken care of sooner than later.
What should you do moving forward?
If you still have mailboxes on-prem, the preferred migration path is to Exchange Online, if you have not done so already.
If you are staying on-prem for some ridiculous reason, you would go to 2016, and eventually to 2019 (you cannot go straight from 2010 to 2019). As well, be aware that the last version that will support the “free” hybrid key is 2016. Therefore, most orgs will be moving to the Exchange 2016 version if their goal is to be in 365 eventually, or if they need to maintain a hybrid server for management. Do not go to 2019 if this is you.
(If you are reading between the lines here, it means that Microsoft will need to come up with a supported way to remove the last Exchange Server while still running Azure AD Connect, and this must happen before the 2016 EOL date–at present it is still not possible–that is, you must keep Exchange 2016 on-prem for hybrid management even if all mailboxes are moved to the cloud).
Last note: at Ignite it was announced that “vNext”–whatever that will be–is going to be offered as a subscription license, and will be continuously updated henceforth–similar to the cloud. Support for 2016 and 2019 will co-terminate in 2025. As well, it will be possible to perform an in-place upgrade from 2019 to the vNext edition. Review other announcements from Ignite here.
