I installed Exchange 2019 on Server 2022 around 9 months ago, as we were on Exchange 2016 on Server 2012R2, been very stable, just need to know the details of vNext seen some articles stating not until the Second Half of 2025 which is confusing as 2019 is planned to go end of life in October 25 ?
- Exchange Server 2016 – Extended support ends October 14, 2025.
- Exchange Server 2019 – Mainstream support ends January 9, 2024. Extended support ends October 14, 2025.
Also Pricing models is it going to be Subscription based will we need Software Assurance?
If you are still on Exchange 2016 then I would suggest upgrading to Exchange 2019
"Microsoft said Exchange Server 2019 will be required to perform an in-place upgrade to Exchange vNext. All the software and hardware requirements for Exchange Server 2019 will be valid for the next Exchange Server version."
