Exchange server 2010 reaches its end of support on January 14, 2020. Microsoft team published official blog posts and updated customers to prepare for the end of support who are still running Exchange Server 2010. We have one year timeline to upgrade from Exchange Server 2010 Organization to latest supported version of Exchange Server On-premises or to Office 365 if your Organization is considering moving to Cloud before end of support date.
Most of the Organizations started their upgrade journey and Organizations already using Hybrid deployment with Exchange Server 2010 and Office 365 started to upgrade their On-Premises environment to Exchange 2016. Organizations who are in middle of their Migration to Office 365 using Exchange Server 2010 can complete the migration before the support end date, and once the migration is completed either decommission the On-premises Environment or if the plan is to continue using long term hybrid then upgrade the On-premises servers to Exchange 2016.
Exchange Server 2019 is now available and fewer Organizations are considering their move to 2019 post upgrading their existing 2010 environment to Supported version Exchange 2013 ( CU 21 ) or later and once the required system requirements for Exchange Server 2019 are met.
Microsoft team published the Exchange 2010 end of support road-map documentation which will be much helpful to plan your upgrade journey from Exchange Server 2010 to Exchange Server 2016 On-premises or to Office 365 ( Fully cloud / Hybrid). This whereto post is written to point you to this essential resource. You also have additional guidance available in the Technical community to assist in this journey and this is the first essential resource to refer before you start your journey,
