NOTE: If you have a Windows 2003 domain controller, the ADSIEdit utility, which is part of the Windows 2003 Support Tools, may not be installed. In this case install the Support Tools by running the Support\Tools\Suptools.msi file located on the Windows 2003 CD. |
Perform the steps described in the related subtopics to ensure that your Exchange environment is ready for migration:
Before implementing Migration Manager for Exchange in your production environment, back up your Exchange infrastructure. We recommend that Active Directory data be backed up at least twice a day during migration.
When Migration Manager for Exchange synchronizes mail, for every megabyte of data migrated from the source to the target, a transaction log file of equal size is generated on the target Exchange server. Exchange-aware backup applications purge the transaction logs after the backup completes. By the time the backup finishes, all logged transactions have already been applied to the store and backed up to tape, making log cleaning safe.
Large transaction logs that are generated during mailbox migration quickly occupy free disk space. To work around this problem, perform one of the following:
Note also that Microsoft recommends turning OFF circular logging on the Exchange server. For more information, refer to Microsoft Knowledge Base article 147524: XADM: How Circular Logging Affects the Use of Transaction Logs.

NOTE: If you skip this step, the Aelita EMW Recycle Bin folder will be created automatically by PFTA during public folder synchronization. |
If you plan to perform public folder synchronization using Migration Manager Public Folder agents, you should create a special public folder called Aelita EMW Recycle Bin.
This folder will help prevent data loss in case of accidental public folder deletion. When a public folder is deleted in one of the environments, the public folder synchronization agents move the corresponding folder in the other environment to the Aelita EMW Recycle Bin folder, if it exists, instead of permanently deleting the folder. You can use this folder to check whether important information has been deleted, and restore any data deleted by mistake.
|
Caution: Only deleted public folders will be put into the Aelita EMW Recycle Bin. If you delete a message from a public folder, it will be destroyed permanently in both the Source and Target Exchange organizations. |
