3 INTRODUCTION The reason for the removal of the first Exchange Server from a site/organization maybe due to server hardware replacement or the exchange was mistakenly installed on a DC. The first Exchange Server in a Site has unique functionality and proper procedural removal is required. The following step assumes that the first exchange server is already running. A new exchange server will be commissioned and the old faithful hardware is than retired from service. The following steps (Proof of Concept) were verified and tested successfully by Abdul Latiff Esa, Chief Technical Officer, of LatiffEsa Technologies, Malaysia. BEFORE SETUP AFTER COMPLETION 3

4 TIMA FRAME DAY 1: VERIFYING AD HEALTH STATUS DAY 1: INSTALLING AND UPDATING DAY 1:VERIFYING CONNECTIVITY DAY 2: SYNCHRONIZING DAY 2: MAILBOX MIGRATION DAY 2: MOVING PUBLIC FOLDERS DAY 2:REPLICATING DAY 2: TESTING DAY 3 : DISABLING EXISTING EXCHANGE SERVER DAY 3 : DECOMMISIONNING EXCHANGE SERVER 4

5 CHECK LIST EXISTING SERVER EXC/EXCFSMO CHECKLIST: Check the existing AD and Exchange Server Health Status Backup System state and DNS folder Upgrade Forest Functional Level to highest level Create a test user, verify all is working fine. Install SUPTOOLS.MSI and run netdom query fsmo, dcdiag & netdiag Replicate AD from ADSS, ensure success Check/Record Event Viewer logs Copy/Backup the OWA Certificate to install on the new server(excnew) Verify nslookup with MX and A record is responding successfully NEW SERVER SETUP CHECKLIST: Install Server 2003 SP2. New Server name is ExcNew. Old Server name is Exc. Ensure The Time Zone and clock is synchronized on all servers. Ensure that the service packs are the same on both servers Install Antivirus software Add the Server 2003(EXCNEW) to the latiffesa123.com Domain as Member Server. Log on to the Domain latiffesa123.com as Administrator. Precede to the section Install IIS and SMTP to setup the new exchange server and at the same time add it to the existing Exchange Organization. NOTE and CARE: PDC & RID on Same Server (avoid with GC) Infrastructure Master & GC OK on same server(if one domain only) Run ipconfig /registerdns on all related servers NO user should be logged on to AD or EXCH during the migration process Decide on an IP address and inform the firewall staffs to update 5

6 INSTALLING EXCHANGE ON THE NEW SERVER Setup IIS and SMTP Control Panel Add remove program Add remove Windows Components Highlight Application Server details Highlight Select IIS details select SMTP and NNTP OK Select ASP.net OK Next Finish.

Start the POP3 and SMTP (default started already) service. Verify the New Exchange Server Setup Create a DNS MX record to support this new mail server Ensure the cost of the new server(mx=9) is lower than the existing(mx=10) Create two new user from ADUC named latiffesa and anitaesa select the new exchange server as the mail server Try to send and receive between both users. MIGRATING USER MAILBOX Migrating the existing mailbox to the new server Start All Programs Microsoft Exchange System Manager Servers Sever name:exc First Storage Group Mailbox Store (EXC) Mailboxes Right click User01 Exchange Tasks Next Move Mailbox Same Administrative Group Move Next The New Exchange Server name should appear here: Next Configure how move mailbox handles corrupted messages in a mailbox: Create a failure report Task Schedule: Next Completing the Exchange Task Wizard: Finish. 6

7 To confirm Successful user Mailbox migration Start All Programs Microsoft Exchange System Manager Servers Sever name: EXC First Storage Group Mailbox Store (EXC) Mailboxes: notice the user is no longer listed under the old server, verify that it s now listed in the new server. Once successful move the others. Don t forget to also move the administrator mailbox or you will get an error while uninstalling the exchange server in the final step. MIGRATIING PUBLIC FOLDERS Moving the entire Public Folder Store (EXC to EXCNEW) This will generate a high Volume of Traffic. First Organization Servers EXC Right click Public Folder Store (EXC) Move All Replicas New Server name: EXCNEW OK All the public folder replicas will now be moved to EXCNEW: OK. Please wait a while (test lab environment with 6 exchange users will take at least 45 min to complete). Once done, everything from EXC will appear in EXCNEW. Moving will be completed once the Public Folder Instances and Replication status folder is empty. 7

Solution: Install the exchange Exchange2003-KB v3-x86-ENU patch. f. Error regarding the Certificate not vailid/expire when moving public folder. Solution: temporary disable SSL on both new server and old. g. Ensure that no users are connected to their mailbox. h. The following error appears when moving mailbox Failed to copy messages to the destination mailbox store. Error: The MAPI call failed. MAPI or an unspecified service provider. ID no: Solution: a) Choose the skip corrupted message option when moving mailbox or b) dismount the store run isinteg -s servername -fix -test alltests or c) Ask the mailbox user to selfarchive the message before moving their mailbox OR try moving the mailbox a few days later(yup, sometimes its possible). i. Cannot connect to OWA from WAN but possible from LAN. Check on the firewall that NAT is updated and the SSL port is opened. Use the telnet <ip address> 443 command, where IP address is the mail server ip. j. Check the Routing group members. Ensure that the master server is configured on the new exchange server, otherwise outgoing (smtp) will not be possible although incoming is OK. a. Routing group b. First routing group c. connector members (master or member) d. Right click and select set as master k. Check the SMTP connector (Routing Groups).
