Hello everybody.

I have Exchange 2013 and 2016 servers in my organization with the latest CU installed. I would like to install a new Exchange server with 2019.

Is it possible that three differente versions (2013, 2016 and 2019) can coexist in the same organization or do I have to remove 2013 before installing a new 2019 server?

Thanks!

    You can have all three in the org since you already have 2013 and 2016 installed in the forest.
