Hi all, i got this job to migrate my Exchange server 2019 mailboxes in DAG to another Exchange server mailbox in DAG hosted on a cloud platform.
I was able to create my 2 other servers and create a second DAG with recplicated DB.
Since my new infrastructure will have a different ip addres, before moving my mailboxes from sv1/sv2 to sv3 and sv4 i would like to create a connector so that migrated mailboxed will redirected to the first DAG. Once all the mailboxes are migrated i plan to change MX records and DNS records to the new public IP Address.
Would you guide me in the creation of this internal connector?

    Sounds like you need a shared SMTP space and continue to point the mx record at the existing Exch Servers

    To configure SMTP Namespace Sharing, you would change the Accepted Domain to an "Internal Relay Domain" and then create a send connector.  An example config would look like this:

    Set-AcceptedDomain contoso.com -DomainType InternalRelay

    New-SendConnector -Name "SMTP Namespace Sharing for Consoto.com" -Custom -AddressSpaces contoso.com -SmartHosts 10.1.1.54 -SourceTransportServers ExchangeServerFQDN

    Once migrated, then you can change the MX record to point to the new infrastructure and set the accepted domain to Authoritative
