Migrating to Exchange

Initial Exchange 5.5 Migration Tasks

Before migrating mailboxes from Exchange 5.5 to Exchange 2000, you must perform initial migration tasks. In addition, the mailbox owners must complete specific initial migration tasks.

To prepare to migrate from Exchange 5.5:

  1. Reduce the amount of Exchange 5.5 data to be migrated as much as possible.
  2. Identify resource mailboxes.
  3. If you need to establish coexistence between Exchange 5.5 and Exchange 2000 while you are migrating Exchange 5.5, or if you require full replication between the Exchange 5.5 directory and Active Directory, install Active Directory Connector and establish an inter-organizational connection agreement.
  4. Ensure that the owners of the Exchange 5.5 mailboxes to be migrated perform the initial user tasks.

Important   When upgrading an Exchange 5.5 server with an Internet Mail Connector configured to forward mail through a smart host, you should take note if the smart host resides in an Exchange 2000 administrative group that consists of multiple routing groups. In such a scenario, Active Directory Connector will designate the first routing group that it finds as the connected routing group for the upgraded SMTP connector (displayed on the connector's Connected Routing Groups tab). Even if the smart host is correctly identified by the SMTP connector, unless the correct routing group is chosen, all messages routed through the SMTP connector will result in NDRs. To prevent this, after migration, manually configure the SMTP connector with the correct connected routing group. (This only applies to administrative groups consisting of more than one routing group.)
