Migrate from Exchange 5.5 Chat Service

If you were using the Chat Service included with Microsoft Exchange Server 5.5, you may have some settings or configurations that you want to continue using when you install Microsoft Exchange 2000 Chat Service. The Chat migration tool enables you to create a new Chat community on an Exchange 2000 server with the name of the Exchange 5.5 Chat server, and with most of the same settings and configurations.

Note   The migration tool will not migrate Chat Service 5.5 extension data. This means that if you had a Profanity Filter or Transcription Extension with your Chat Service 5.5, it is now necessary for you to migrate these manually, so that they will work with Exchange 2000 Chat Service.

The new Chat community you create with the migration tool will be totally separate from your Exchange 5.5 Chat server. Also, if your Exchange 5.5 Chat installation consisted of one Chat service, spanning a network of two or more Exchange servers, be aware that this type of chat installation is not supported by Microsoft Exchange 2000 Server. Using the migration tool, you can create similar Chat communities on each of your Exchange 2000 servers. Each of the Exchange 2000 Chat communities on each of the Exchange 2000 servers in your domain will operate separately, with separate user lists and channel lists.

To migrate to Microsoft Exchange 2000 Chat Service from the previous version:

1. Install Windows 2000 Server on your target machine, creating a new domain, or configuring it as a member server of an existing domain.

   Note   For this procedure, the source of the migration tool is the Exchange Chat Service 5.5 server. The target of the migration tool is the Exchange 2000 Chat Service server.

   If you are installing Exchange 2000 on a network of servers on which Chat Service 5.5 spanned two or more servers, upgrade all of the machines to Windows 2000 Server, creating a new domain, or configuring each as a member server of an existing domain. All the machines must be in the same domain.

2. Exchange 2000 Chat Service and Chat Service 5.5 have the same display name, "Microsoft Exchange Chat." If you are installing Exchange 2000 Chat Service on a machine where Chat Service 5.5 is now located, you must:
3. • Open the properties on Microsoft Exchange Chat Service 5.5 and manually modify Display Name using the Services node of the Computer Manager MMC snap-in.

   • Note   A possible name to use is "Microsoft Exchange Chat 5.5," but you can enter any name.

   • Reconfigure the ports so Chat Service 5.5 is not using the default port 6667 or the alternate default port 7000.

   Caution   If this step is not completed, Exchange 2000 setup will fail to install Chat Service. However, this step is not necessary if the target is a different machine than the source.

4. Install Exchange 2000 Chat Service on each target machine.
5. Run the Chat migration tool (chatmig.exe) from the exchsrvr\bin directory, and specify the target. The target must be the administration group to which you want to migrate Chat.

   After you run the migration tool, a new Chat community is created on the Exchange 2000 server with the name of the 5.5 Chat server, and with similar server, channel, ban and class configurations. Until you are ready to cut over to the Exchange 2000 server, both Chat services can run simultaneously.

   • If you are installing Exchange 2000 Chat Service on a separate machine from the one where Chat Service 5.5 is installed, copy the migration tool from the exchsrvr\bin directory on the target machine to the source machine. Run the Chat migration tool, identifying the Chat Service 5.5 directory as the source, and the Exchange 2000 Chat Service directory as the target.
   • If you are installing Exchange 2000 Chat Service on a network on which Chat Service 5.5 spanned two or more servers, select one server to use for the base configuration. Run the chat migration tool on that selected server first.
6. Verify that all the configuration is migrated to the Exchange 2000 Chat Service using the MMC snap-in.

   Tip   You can also check the chatsetup.log that the migration tool produces. This log will be located in the exchsrvr directory.

   Note   The migration tool will not migrate Chat Service 5.5 extension data. This means that if you had a Profanity Filter or a Transcription Extension working with your Chat Service 5.5, it will be necessary for you to migrate this manually so that it will work with Exchange 2000 Chat Service.

   If you are installing Exchange 2000 on a network of servers on which Chat Service 5.5 was installed on two or more servers:

   • On the machine you have selected to use for base configuration, use the MMC snap-in to make sure the new Chat community and the associated configuration was created.
   • On the base machine, using the Exchange 2000 System Manager IRCX protocol snap-in, verify that the community created during migration is set to be hosted by this server.
   • On all the other machines in the 5.5 Chat network, using the Exchange 2000 System Manager IRCX protocol snap-in for each server, configure the server to host the Chat community created during the migration of the first server. Configure the IP address and ports to be used, as well as any extensions.
   • Run the migration tool on each of the other machines that were in the 5.5 Chat network, creating a new Exchange 2000 Chat community on each.

   Important   Once a Chat Service 5.5 network has been migrated, each of the servers will operate independently, with separate user lists and channel lists. Exchange 2000 does not support spanning a Chat network across multiple servers.

7. Uninstall Chat Service 5.5 using the uninstaller shipped with Exchange Server 5.5.
