Hello everyone
There are two Exchange 2016 servers and 4 Exchange 2019 servers to which mailboxes are migrated. All servers are located in the same Active Directory site and look at the same two EDGE servers.It is necessary to redirect mail traffic through the new servers. I made a new subscription on the new 4 servers.
Question: Tell me, please, do I need to delete the subscription from the original two Exchange 2016, or is it not necessary - as soon as the servers themselves are removed from operation after migration?
It just so happened that I signed new servers on EDGE and deleted the subscription from the original ones by clicking A (All), then executed the get-edgesubscription command on the new servers and saw that there was no subscription. As I understand it, this subscription is the same for all 6 servers, or is it the same. or am I doing something wrong?
Thanks!

Yes, I understand. Then I need to make a new re-subscription from any of the 6 servers- that the new servers could send mail through the original EDGE? And after the migration is complete, just remove the original servers from the infrastructure and then renew the subscription again, right?
Hi @Cobion ,
Are the Exchange2016 servers deactivated after the migration is complete? It is best if you remove the unused servers to prevent problems, how did you remove the edge subscriptions? You can do so by referring to the steps in the documentation:
Procedures for Edge Subscriptions
From the documentation, you will need to delete and redo the edge subscription or the new server will not sync.
