DOCUMENT:Q155216 23-MAR-2002 [exchange] TITLE :XADM: How to Move Exchange Server to a New Computer w/ Same Name PRODUCT :Microsoft Exchange PROD/VER::4.0,5.0,5.5 OPER/SYS: KEYWORDS:kbenv kbusage exc4 exc5 exc55 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 ------------------------------------------------------------------------------- SUMMARY ======= It may be necessary, because of performance or other reasons, to replace a Microsoft Exchange Server computer with a new, more powerful system. This article explains how to move Exchange Server to a new computer, if the original computer will be off the network and the new computer will have the same name as the original computer. MORE INFORMATION ================ Before you move Exchange Server to the new computer, verify that the original computer is not the only Microsoft Windows NT domain controller in the domain. While this computer is shut down as part of the moving procedure, there must be a domain controller that can validate logon requests. If the original computer is a Primary Domain Controller (PDC), make sure that there is at least one other backup domain controller (BDC) in the Windows NT domain. After you shut down the original computer, upgrade the BDC to a PDC. If the original computer is a BDC, make sure that the PDC in the domain is up and operational, or that there are other BDCs that can be upgraded to become the PDC. The steps below explain how to move Exchange Server to a new computer that has the same hardware platform as the original computer. That is, either both computers are Intel, or both computers are Alpha. For the purposes of these steps, the two computers are referred to as the "original computer" and the "new computer," even though both computers have the same NetBIOS computer name. How to Move Exchange Server to a New Computer with the Same Name as the Original Computer ----------------------------------------------------------------------------------------- To move Exchange Server to a new computer consists of the following steps, which are expanded later: 1. Backing up information from the original computer. 2. Installing Windows NT and Exchange Server on the new computer. 3. Installing Windows 2000 and Exchange Server on the new computer. 4. Restoring the Exchange Server data to the new computer. 5. Configuring the Key Management server (KM server). 6. Restoring and reconfiguring connectors. Backing Up Information from the Original Computer: 1. At the original Exchange Server computer, start the Exchange Server Administrator program. Note the following information: - The organization and site names. - The configuration parameters of any connectors that are installed on the original computer. You may want to print screen dumps of the different pages of the connector properties. Quit the Exchange Server Administrator program, and then note the drive configuration of the original computer. 2. At the original computer, stop all of the Exchange Server services. 3. Copy the entire Exchsrvr directory to another computer on the network, or to a tape drive. If the log, database, and working directories are on different drives, make sure that you copy the Exchsrvr directories from every drive. 4. Start the Exchange Server Performance Optimizer utility, and then note the locations of the directory service, information store, message transfer agent (MTA), and Internet Mail Service files. You can quit the Performance Optimizer utility after you get the necessary information. You can also get this information from the registry. You may want to run the perfwiz -v command, and then note any customized settings on the original computer. Also, note the version and service pack number of Exchange Server that is installed on the original computer. 5. If the KM server service is installed, stop the KM server service, and then back up the Security directory. If the original computer is running Exchange Server version 5.5, there is no Security directory, because the KM server information is stored in the Exchsrvr\Kmsdata directory. Also back up the KM server Startup disk. 6. Shut down the original computer, and then turn it off. Make sure that there is an operational domain controller in the Windows NT domain. Installing Windows NT and Exchange Server on the New Computer: 1. Using the Server Manager utility, remove the computer account for the original computer, and then re-add it. 2. Install Windows NT on the new computer, using the same computer name that the original computer used. If necessary, make the new computer a BDC. Ensure that the original computer is turned off before you install Windows NT on the new computer. 3. Reconfigure the drives on the new computer exactly as they were configured on the original computer. Installing Windows 2000 and Exchange Server on the New Computer: NOTE:If the server is not a domain controller, do not perform step one and proceed to step 2. 1. Run the Active Directory Installation Wizard (DCPROMO) to demote the server to a member server. 2. To disjoin the server from the domain, click Properties, click the Network Identification tab, click Properties, and then click Workgroup. 3. In Active Directory Users and Computers on a domain controller, remove the computer account that corresponds to server that you have just removed from the domain. 4. Install Windows 2000 on the new computer, and then name the computer the same computer name that the original computer used. Ensure that you reconfigure the drives on the new computer exactly as they were configured on the old computer. 5. Join the server to the domain. NOTE: It may be necessary to run the Active Directory Installation Wizard (DCPROMO) to promote the member server to a domain controller. Restoring the Exchange Server Data to the New Computer: NOTE: When you install Exchange on the new server, create a new site with the same site name, organization name, and server name as the previous server being replaced. DO NOT join the site. 1. Install Microsoft Exchange 5.5 on the new server, and then click the option to create a new organization. When you receive the prompt, use the same organization and site names that were used on the original server. Install the same service packs and hotfixes that were installed on the original server. 2. Run the Performance Optimizer utility and verify that all of the paths are the same as those noted in the previous steps. 3. Stop the Exchange System Attendant Service (MSExchangeSA) from either the Control Panel services interface or from a command prompt type "Net Stop MSExchange" (without the quotation marks). This procedure stops all other Exchange services as well. 4. Copy the Exchsrvr directories that you backed up from the original computer over the Exchsrvr directories on the new computer. Make sure that you copy the directories to the correct drives. If the original computer and the new computer do not have the same hardware platform, then only copy the Dsadata, Dxadata, Imcdata, Mdbdata, and Mtadata directories. You may also need to copy the Ccmcdata, Insdata, Kmsdata, and Tracking.log directories if the corresponding components were installed or enabled on the original computer. 5. Start the system attendant and directory services. 6. Start the information store service. If the Application event log states that you need to run Isinteg -patch when you start the information store, at a Windows NT command prompt, run the following command isinteg -patch and then restart the information store service. Configuring the KM Server: You installed the KM server in the "Installing Windows NT and Exchange Server on the New Computer" section, step 7, before you restored the Exchange Server directory from the original computer to the new computer. 1. Stop the KM server service on the new computer. 2. Copy the Kmspwd.ini file from the KM server Startup disk for the original computer to another disk. Label the disk "KM Server Startup Disk - New Computer." 3. Perform one of the following steps, depending on the version of Exchange Server that the original computer was running and the new computer is running: - For Exchange Server version 4.0 or 5.0, at the new computer, rename the Security\Mgrent directory to the Security\Mgrent.original directory. Copy the Security\Mgrent directory from the backup of the Security directory of the original computer (that you made in the "Backing up Information from the Original Computer" section, step 5) to the Security directory on the new computer. - or - - For Exchange Server version 5.5, at the new computer, rename the Exchsrvr\Kmsdata directory to the Exchsrvr\Kmsdata.original directory. Copy the Exchsrvr\Kmsdata directory from the backup of the Exchsrvr directory of the original computer (that you made in the "Backing up Information from the Original Computer" section, step 3) to the Exchsrvr directory on the new computer. 4. Place the new KM server Startup disk for the new computer (labeled "KM Server Startup Disk - New Computer") into the disk drive of the new computer. 5. Start the KM server service on the new computer. 6. Use the Performance Optimizer utility to make any desired changes. 7. Start all of the Exchange Server services. Restoring and Reconfiguring Connectors: Restore all of the information that relates to site connectors and X.400 Connectors on the new computer. You need to reconfigure any Internet Mail Connector or Dynamic RAS Connectors. You may also need to reconfigure third-party connectors. Exchange Client Profiles ------------------------ After you complete the steps in this article, Exchange Server runs on the new computer in the same way that it ran on the original computer. Exchange Clients can connect to the new Exchange Server computer just as they connected to the original computer. Use of Offline Backups Instead of Online Backups ------------------------------------------------ In the procedures in this article, you use an offline backup, instead of an online backup. This allows you to move all of the data that existed at the time that the Exchange Server services were stopped to the new computer. This includes data that may have arrived after the last online backup, as well as transient data in the MTA or connector queues. If you perform an online backup, to be sure that you move all of the data to the new computer you need to copy transaction logs, as well as the MTA and Internet Mail Service data files. It is more effective to copy the entire Exchsrvr directory on each drive to the new computer. This procedure requires that you configure the locations of the different logs and databases exactly the way they were configured on the original computer, but it guarantees that there is no loss of data.
