The table below lists the preparation steps for the source and target environment that must be accomplished before you start the migration process.
You can find the detailed explanations and procedures for each step listed below in the Quest Migration Manager Installation Guide. The Quest Migration Manager System Requirements and Access Rights document will help you to set the required permissions for Active Directory and Exchange migration with Migration Manager.
|Check the software requirements
Before installing Migration Manager, make sure that the following servers meet the software requirements:
Any computer that does not meet these requirements should be upgraded before installation of Migration Manager.
|System Requirements and Access Rights
|Prepare the source and target environments for Active Directory migration
|Prepare the source and target environment for Exchange migration
|Connect the source and target Exchange Organizations using the SMTP connector
|Set the required permissions

Planning migration without trust established
If you are planning an Exchange migration using Migration Manager for Exchange without having trusts established, you will need to perform the following actions:
To configure the Client Profile Updating Utility for Microsoft Outlook profile processing if trust relationships are not established between the source and the target domains, refer to the Client Profile Updating Utility Administration Guide.
When trusts are required
The above specified procedure is valid for the most every cases, but there are some exclusions in specific environment:
This section describes the common issues you may face if you perform an inter-forest migration using Migration Manager for Active Directory without having trusts established. In such an environment, the source and target directories are isolated one from another and there might be no transition period when both source and target accounts can be used. But the migration can still be performed without critical restrictions if the accounts are switched correctly.
Take the following steps to perform the migration:
These steps can be performed during working hours.
The following steps should be performed one right after another or during non-business hours:
The last two steps make up the user switch.
NOTE: Microsoft SQL servers should be processed during non-business hours because the SQL Processing Wizard replace the source accounts with the target accounts specified in permissions when processing such SQL servers.
Each of these steps is described in more detail below.
For a successful migration, the computer on which Migration Manager is installed must belong to the target domain.
Migrate the Directory
Migrate accounts from the source to the target domain in migration sessions.
The only two restrictions on this step are as follows:
Update Distributed Resources and Microsoft Exchange and SMS/SCCM Servers
In Resource Updating Manager, add the computers to be processed and specify the administrative accounts for the processed computers (see the Resource Updating Manager online help for details).
When reassigning permissions and group membership to target users and groups with Resource Updating Manager or one of the processing wizards, select the Leave source accounts permissions check box to preserve resource access for the source accounts. This is required since the users continue using their source accounts until they are completely switched to the target accounts.
Switch to the Target Domain
The following operations should be performed one right after another or during non-business hours:
After that, users begin to use the target accounts.
After resources are processed and users can access their resources using target accounts, you can clean up the source accounts’ permissions and disable source accounts.
