exchange 2013 to 2019 migration

Brass Contributor

Looking at the exchange 2013 migration path, for coexistence I found what it seems an error in the online documentation at the following links

Exchange Server 2019 system requirements, Exchange 2019 Requirements, Exchange 2019 Memory Requireme...

 

it says for 2016 that no previou exchange relesase are supported for coexistence.

That's clearly wrong. Where can we find correct information for upgrade planning

Since Exchange Server 2013 ended support on April 11, 2023, the official technical documentation states:
It is stated that there is no previous version in a concurrent support scenario in Exchange Server 2016.

But technically it is possible.
