Appendix: If You Use the Previously-Released, Converted Exchange Server 2007 Management Pack

Applies To: Exchange Server, Operations Manager 2007 R2

You may be using the previously released version of the Exchange Server 2007 converted management pack. It is not possible to upgrade from the previously released, converted management pack to this new, native version of the Microsoft Exchange Server 2007 Management Pack.

This section describes options to help you decide how to migrate from the previously released, converted management pack to the new, native management pack. The options are as follows:

• Delete the previously released, converted management pack. Then import the native Exchange Server 2007 Management Pack.

• Keep the previously released, converted management pack and use a second management group for the new, native management pack. In this scenario, you introduce and tune the native management pack by using a second management group and multi-homing the Exchange 2007 agents to report to both management groups. You should disable the Exchange 2007 synthetic transactions from one of the management groups because synthetic transactions consume CPU, disk IO, and memory resources on the Exchange 2007 servers. We recommend that you disable the converted management pack synthetic transactions as soon as possible because the native management pack synthetic transactions use fewer resources on the Exchange 2007 servers.

• Keep the previously released, converted management pack, and plan a gradual introduction of the new, native management pack by enabling server role discoveries on a server-by-server basis. You can gradually introduce the new, native management pack into the existing management group. This is possible because the server role discoveries in the new management pack are disabled by default. You can enable the discoveries of the new Management Pack on a server-by-server basis (see Enable Exchange 2007 Server Role Discovery). As you enable servers to be discovered by the new management pack, you can disable the discoveries for the same servers in the converted management pack. You must run the Operations Manager 2007 remove-disabledMonitoringObject cmdlet in order to remove the converted management packs objects from the management group and avoid running synthetic transactions from both management packs at the same time.

If you are running both management packs in parallel on the same server, you should disable synthetic transactions from one of the management packs. The table provides information to help you identify and disable the duplicate set of synthetic transactions. For reference, see the information about the transaction rules in the converted Exchange Server 2007 Management Pack.

If you are keeping the previously released, converted management pack and doing a gradual introduction of the new, native management pack, as you enable servers to be discovered by the new management pack, disable the discoveries for the same servers in the converted management pack. In this way, you can remove the converted management pack on a server-by-server basis.

This section provides information to help you migrate settings from the converted Exchange Server 2007 Management Pack.

The following table lists possible targets that you can have for overrides in the converted management pack and the corresponding targets that may be required in the native management pack. Note that in some instances, many targets are possible because the native management pack has a richer model.
