Upgrade an Exchange 5.5 Connector

Upgrading your Exchange 5.5 connectors to Exchange 2000 connectors can be a normal part of your Exchange 2000 installation. You simply need to install the connector you want. The sections on the specific connectors contain information about configuring the connectors once you've installed them.

Important   Although the connection settings are saved during an upgrade, you must reconfigure the import and export containers, the schedule of directory synchronization, the address space used for message routing, and delivery restrictions such as message size.

Note   Trust level information on Exchange 5.5 import and export containers is obsolete in Exchange 2000, and is deleted during upgrade.

When you upgrade from Exchange 5.5 to Exchange 2000, you perform the following general steps:

1. Upgrade the operating system from Windows NT 4.0 to Windows 2000.
2. Install and run the Exchange version of the Active Directory Connector (ADC) to populate Active Directory on the server with information from the Exchange 5.5 directory.
3. Upgrade Exchange 5.5 to Exchange 2000.

You can find out how to upgrade to Windows 2000 by using Windows 2000 documentation. Information about upgrading Exchange 5.5 to Exchange 2000 is contained in Microsoft Exchange 2000 Planning and Installation.
