Migrate Exchange Server 2013 to Exchange Server 2019

Hello everybody, 

We want to do the migration more or less in the current operation, of course with one or the other service interruption. Now it is a bit difficult for me to find out at which points we have to warn our users that it might come to failures. Could someone show me these points? 

Thank you very much

    Migrating Exchange Server 2013 to 2019 is probably the easiest migration you can do as both servers are almost the same. Both can up- and down proxy, if you use different hostnames for both Exchange Servers and have a certificate with both names on them. In our guide at Migrate Exchange Server 2013 to Exchange Server 2019 in a SBS migration scenario we use the same DNS hostnames for the 2013 and 2016 servers and that can cause a DNS loop if you do the migration during office hours. Either do the migration over the weekend and finish it or configure using different FQDN's and certificates.

    Thanks for the answer. I can use different hostnames, but one FQDN because of the certificate.

    But from which point of the migration should I work off office hours? In other words - until which point can I work without off time?

    Thanks
