Reference Materials for Migration 8.15 - Post-Migration Activities

Post-Migration Activities

After migration has come to an end and you are absolutely sure that all the objects have been successfully migrated to the target environment, you might want to perform the following activities:

1. Stop the mailbox and calendar synchronization jobs for migrated servers and uninstall the mail and calendar agents.
2. Stop the public folder synchronization jobs for migrated folders and uninstall the public folder synchronization agents.
3. Stop the Free/Busy synchronization and uninstall the Free/Busy Synchronization agent.
4. Stop directory synchronization.
5. Disable source accounts.
6. Clean up the service attributes used for migration.
7. Clean up SIDHistory attributes.
8. Clean up permissions for legacy accounts.
9. Decommission the migrated Exchange servers and collapse the source Exchange organizations.

Stop the Mailbox and Calendar Synchronization Jobs

When all the mail data from a server is migrated to the new Exchange servers, you can stop the mailbox synchronization job and uninstall the mail agents. By this time all the users who had mailboxes on the server should already use their target Exchange mailboxes.

If you do not need to synchronize Calendar details (appointments and meetings), you can also stop the Calendar Synchronization Agent.

To stop and uninstall the agents, take the following steps from the Migration Manager console:

1. Right-click the source server and stop the Mail Source Agent, the Calendar Synchronization Agent (if running on the source server), and the Transmission Agent. Alternatively, you can right-click a job in the management tree and click Stop All Agents on the shortcut menu. Note that the Transmission Agent can also be involved in public folder synchronization; in this case you should not stop it.
2. If the target servers do not participate in any other mailbox synchronization jobs, stop the Mail Target Agent on each of the target servers.
3. Delete the mailbox and calendar synchronization jobs for the server.
4. Uninstall the stopped agents by clicking Install/Uninstall Agents on the Actions menu.

Stop the Public Folder Synchronization Jobs for Migrated Folders

After all the users have been switched to the target servers and are using the target public folders, you can stop the public folder synchronization jobs, as follows:

1. Right-click each of the source and target servers and stop the Public Folder Source Agent, the Public Folder Target Agent, and the Transmission Agents. Alternatively, you can right-click a job in the management tree and click Stop All Agents on the shortcut menu. Note that in this case you might occasionally stop an agent that is involved in other synchronization jobs, for example if public folders from different source servers are synchronized with the same target server.
2. Delete the public folder synchronization jobs.
3. Uninstall the stopped agents by clicking Install/Uninstall Agents on the Actions menu.

Stop the Free/Busy Synchronization Job

After all the users get switched to the target servers, you can stop the free/busy synchronization job and uninstall the Free/Busy Synchronization Agent, as follows:

1. Right-click each of the source and target servers and stop the Free/Busy Synchronization Agent. Alternatively, you can right-click a Free/Busy synchronization job in the management tree and click Stop All Agents on the shortcut menu.
2. Delete the Free/Busy synchronization job.
3. Uninstall the stopped agents by clicking Install/Uninstall Agents on the Actions menu.
