Testing the SMTP Connectors (Optional)
After both source and target Exchange organizations have been set up for Internet mail flow as well as both source and target DNS servers have been configured for mail forwarding, it is recommended to test the connection between the source and the target organizations.
Caution: This step should be performed in coordination with the administrator of the Exchange organization.
To test the SMTP connectors:
- Create test mailboxes on the source and target Exchange servers. In this example, both mailboxes will be called mbx1.
- Set the same primary SMTP address for both mailboxes.
- In this example the primary address for both mailboxes will be mbx1@Westland.Exchange.com.
- Set additional addresses for both mailboxes.
- In this example additional address for the source mailbox will be email@example.com, and firstname.lastname@example.org for the target mailbox.
- Create a contact on the source Exchange server and point it to the additional SMTP address of the target Exchange mailbox (email@example.com).
- Create a contact on the target Exchange server and point it to the additional SMTP address of the source mailbox (firstname.lastname@example.org).
- Open the test source mailbox and send a message to the source contact.
- Open the test target mailbox and make sure that the message has arrived.
- From the test target mailbox, send a message to the target contact, and make sure the e-mail has reached the source test mailbox.
Appendix A: Exchange 2003 to Exchange 2010 Migration Restrictions
Exchange 2003 organization to Exchange 2010 organization migration scenario is not supported, if MSA or CSA is installed directly on the source Exchange 2003 server and one of the following situations takes place:
- Custom administrator mailbox is used as the administrator mailbox in the Exchange 2010 organization and Exchange 2010 organization does not have public folder store, or
- System Mailbox is used as the administrator mailbox in the Exchange 2010 organization
This issue is caused by the difference between the Exchange 2003 and Exchange 2010 MAPI logon methods that prevents logging on to Exchange 2010 through Exchange 2003 MAPI. To work around the issue, you need to use separate agent hosts for MSA or CSA instead of installing them directly on the source Exchange 2003 server.
NOTE: For detailed information about system requirements for agent hosts, see the Exchange Migration Agents section of the System Requirements and Access Rights document.
