exchange 2013 to 2019 migration
Looking at the exchange 2013 migration path, for coexistence I found what it seems an error in the online documentation at the following links
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

You're right to be cautious — the documentation around Exchange 2013 to 2019 migration can sometimes be confusing, especially regarding coexistence. Officially, Exchange Server 2013 cannot coexist directly with Exchange Server 2019, as Exchange 2016 is the only supported intermediate version for coexistence with 2019. That means for a native path with coexistence, you would typically need to migrate to Exchange 2016 first, then to 2019.However, if you're looking to migrate directly from Exchange 2013 to Exchange 2019 without setting up coexistence, you might want to consider using a third-party solution.
We recommend EdbMails Exchange Migration software, which supports direct mailbox migration from Exchange 2013 to Exchange 2019. It handles everything from mailbox mapping to secure data transfer using modern authentication, and it doesn’t require double-hop upgrades or intermediate servers. This can save you significant time and complexity, especially for small to mid-sized organizations.

- 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.
Please refer to the following link!
https://techcommunity.microsoft.com/t5/exchange-team-blog/best-practices-for-migrating-from-exchange-server-2013-to/ba-p/3773084/?WT.mc_id=M365-MVP-5002523- I wonder if somewhere is still available a link to the "old" requisites where exchange 2013 was still present as well as the AD functional level, which now stated Windows 2012R2 as minimum.
thanks- it's possible.
