Guidelines for Server Configuration

The following rules and guidelines apply to server configuration:

• You must upgrade a Messaging or Calendar Server to version 6 before you can configure it to use Schema 2.

• We recommend that you upgrade the Messaging and Calendar servers before you migrate to Schema 2.

• When you upgrade a server to version 6, you can configure it to use Schema 1 (until the directory data has been migrated).

• After you migrate the directory data to Schema 2, you can reconfigure the server to use Schema 2.

• If you migrate the directory data to Schema 2, compatibility mode, configure the servers to use Schema 1.

  After you migrate the directory data from Schema 2, compatibility mode to Schema 2, native mode, you must reconfigure the servers to use Schema 2.
