Step 2 (optional): Configure ongoing dirsyncs

Conditional Step: This step applies only if you are using the Quest CMN product for ongoing directory updates after the migration.

If you want to keep your Notes environment up and running with an active Domino directory for a period after the migration, or indefinitely, you may want to configure the Quest CMN Directory Connector to run regular directory updates for as long as the Notes and Exchange environments coexist.

Step 3: Update mail routing

Migrator for Notes to Exchange is commonly used to automatically update mail forwarding in both systems to ensure proper routing during the migration. Migrator for Notes to Exchange can set and remove forwarding rules in both environments, as long as the mail routing domains or smart hosts are properly configured.

When the users and groups are all migrated, routing can be permanently updated to direct external incoming (Internet) mail to Exchange instead of to the Notes environment. This step includes modifying the MX record(s) to point to Exchange. In some environments, updating mail routing also includes updating routing tables and/or firewall modifications.

Most organizations prefer to update mail routing only after the last user has been migrated, to minimize change before and during the migration process. But the MX modification actually can occur at any time after all Notes users have been provisioned into Active Directory as mail-enabled objects. (If routing is updated to send inbound mail to Exchange before a particular user is provisioned, there will be no forwarding address in AD to relay the user’s mail back to Notes.)

Step 4: Post-migration "clean up"

To clean up after the last user has been migrated:

1
Verify the Notes server is inactive. Make sure that the Notes server is no longer processing mail traffic or utilized for active applications.
2
If you were using SMTP mail coexistence: Delete the temporary mail routing MX domain(s) you created in the Pre-migration preparations, to support routing between Notes and Exchange during the transition. Now that all users have been migrated to Exchange and inbound traffic is routed directly to Exchange, the temporary routing domain(s) should no longer be required.
3
If you no longer need the Notes environment: After you have verified Notes is inactive, you may take a final backup and decommission the environment.
