Migration from SBS 2011 to Exchange 2016 on-premise guide

Hi,

I'm just following the guide, and am at the stage where I need to migrate mailboxes, however, I can't see anywhere in the guide where it states to change mail flow of the incoming email (port 25) from the old SBS 2011 to the new Exchange 2016 server IP, and also I think that the new Exchange server would also need to have a send connector created at that point as well?

I think once the mailboxes have migrated over to the new server, it is at that point that the SMTP port should be changed to the new server, and I'm guessing that this should also be the point where the send connector should be created too. 

Thanks,

Mike

    Mike,

    During the migration of the mailboxes and with both Exchange Servers still installed it does not matter where port 25 is routed to. Exchange Server will deliver mail to a mailbox even it already lives on the new Exchange Server.

    Before you uninstall the old Exchange Server you either need to remove the Sendconnector that is still bound to the old server or you can change the value SourceTransportServers from within EMS on the new Exchange Server, see below example.

    [PS] C:\Windows\system32>Get-SendConnector | Ft Identity,Enabled,SourceTransportServers

Identity               Enabled SourceTransportServers
--------               ------- ----------------------
Default Send connector    True {EXCH2013}


[PS] C:\Windows\system32>Get-SendConnector | Set-SendConnector -SourceTransportServers EXCH2013,EXCH2016
[PS] C:\Windows\system32>Get-SendConnector | Ft Identity,Enabled,SourceTransportServers

Identity               Enabled SourceTransportServers
--------               ------- ----------------------
Default Send connector    True {EXCH2016, EXCH2013}


[PS] C:\Windows\system32>
