Upgrading from MOM 2000 SP1 to MOM 2005 SP1

This section provides information about upgrading the Microsoft Operations Manager (MOM) SP1 components installed on a single computer. If you have the MOM 2000 SP1 components installed across multiple computers, see the Microsoft Operations Manager 2005 Deployment Guide.

When you upgrade MOM 2000 SP1 components to MOM 2005 SP1, the MOM 2000 SP1 components on the computer are uninstalled and the MOM 2005 SP1 versions are installed in their place using the existing configuration settings, with the exception of the MOM database and MOM Reporting.

While you are upgrading your environment from MOM 2000 SP1 to MOM 2005 SP1 it will temporarily be in a mixed mode where there are both MOM 2005 SP1 and MOM 2000 SP1 agents reporting to MOM 2005 SP1 Management Servers and, possibly, to MOM 2000 SP1 DCAMs.

It is important to review the Before You Begin section earlier in this guide. It references important documents to review before you upgrade to the MOM 2005 SP1. For example, hardware and software requirements may have changed since you installed Microsoft Operations Manager 2000 SP1. This information is contained in the Microsoft Operations Manager 2005 Supported Configurations data sheet.

Also, for information about mixed mode transition, refer to the note in Table 14.1 MOM Interoperability (Part 1), which provides information about using the transition Management Pack (MicrosoftOperationsManagerTransition.akm).
