Microsoft Exchange End of Support: Migration Options and Important Dates

Microsoft Exchange solutions | Binary Tree

As you should (must) know by now, Microsoft is ending Exchange 2010 support this October. At that point, Microsoft will no longer provide technical support for Exchange Server 2010, including bug fixes, security fixes, and time zone updates. Your installation of Exchange 2010 will continue to run after this date, but the risks may outweigh the benefits. If you are still running Exchange 2010, act now and modernize your environment.

Logically, upgrading to Exchange Server 2013 or ideally 2016 to remain secure and supported would be your next step. But what most people don’t realize is that Exchange 2016 mainstream support will also end this October. From that point forward, Exchange 2016 will be in extended support. This means no more updates and only security fixes will be released when these updates are marked as ‘critical’. It also means currently only Exchange 2019 remains in Microsoft’s mainstream support, but that too has an end date.

Inevitably, strategically planning for your path to the cloud should begin now if already not underway. However, if you cannot move your mailboxes to the cloud and you plan on keeping mailboxes on-premises, then you really should be moving to Exchange Server 2019 and using that for both mailboxes and hybrid connectivity. That way you get full Microsoft support including non-critical bug fixes and get ongoing product improvements. 

Whatever you decide for your business, at least consider the various paths to modernize. Below we have listed all the Microsoft migration options based on source to target.

Microsoft Exchange Migration Options:

  • Exchange 2010 Exchange 2016 Exchange 2019
    • Note. There is no direct upgrade path from Exchange 2010 to Exchange 2019
  • Exchange 2010 Office 365
  • Exchange 2013 Exchange 2016
  • Exchange 2013 Exchange 2019
  • Exchange 2013 Office 365
  • Exchange 2016 hybrid (all mailboxes are in Exchange Online) You are safe to stay in this situation until Microsoft releases a final solution for that dreaded last Exchange server on-premises for management purposes
  • Exchange 2016 hybrid (all/some mailboxes remain on-premises) Exchange 2019 hybrid (in order to stay in a supported configuration)
  • Exchange 2016 Office 365
  • Exchange 2019 Office 365
