Hi, one of our clients has a fully updated/patched Exchange 2013 installation running on Windows Server 2012R2.
They now asked me to migrate Exchange 2013 to Exchange 2019 CU13 and get rid of the old server.
I see that from Exchange 2019 CU12 and up, Windows Server 2022 is fully supported so I prepared a new server with that OS.
Does anyone know if running it this way will cause issues having this in a coexistent state? I don't see why but I haven't yet seen this combination of Exchange versions working together.. If there is anything really important I need to be aware of any tips would be appreciated.
