PROBLEM:
How to Migrate a Relay Connector in Microsoft Exchange 2013 or 2016

SOLUTION:

* Step 1 and 2 can be skipped if you are not keeping the current IP for your relay connector *

1.)  Add a temporary IP address to the current or Old exchange server.
2.)  Run the following power shell command to migrate the connector and the remote IP Ranges.

Code Select Expand

New-ReceiveConnector "Relay Connector Name" -server SERVER_NAME2 -Bindings 192.168.0.102:25 -RemoteIPRanges (Get-ReceiveConnector "SERVER_NAME1\Relay Connector Name").RemoteIPRanges -TransportRole "FrontendTransport"

Note: IP (192.168.0.102 is a stand in for what you made the temporary IP. You will need to change it in the command.

3.)  On the old exchange server, remove the IP.
4.)  Add that IP to the new Exchange Server.
5.)  Assign the IP to the connector.
6.)  Remove temporary IP from new exchange.
7.)  Allow anonymous relay with the following PowerShell command:

Code Select Expand

Get-ReceiveConnector "Relay Connector Name" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"

3.)  Go to Scoping > "*Network adapter bindings:" click add
4.)  Choose "Specify an IPv4 address" and type in the IP Address.
