Migrate Exchange 5.5 to Exchange 2003 Server:

• install Active Directory, and using Active Directory migration tool from Installation CD to move user accounts.
• Complete the installation of Exchange 2003, then run Migration tool to move mail boxes

An affordable and necessary disaster recovery plan (andrp):

Backup plan:

·        Two identical servers are deployed. One is in production (EXDCS2), the other one is also on-line, but renamed to EXDCS1, IP: 192.168.23.6, All Exchange services stopped.

·        A rescue server is taken off-site.

·        DCS2 (Exchange server): Use the built-in Backup function to backup System State and Storage Store to K: (300GB) unattended.  This backup is done 5AM every workday. File names are created automatically, such as “Small Business Server Backup (1).bkf”.  Disk 0 and Disk1 of this server are configured as RAID 1, i.e. mirrored.

·        DCS1 (Recovery Server) has Exchange fully configured and tested. Its services have been stopped.  A free download program “idem” is running. Idem would back up server DCS3 Shared folder at every 1 hours interval (1 hour, the value=400).  It also backup DCS2 Exchange Storage store at the same interval.

·        DCS3 Backup: Unattended daily backup to D:. Shadow copy is created every 6 hours, starting 6AM every day.  If files are modified, a shadow copy will be created. User can see the copied from local computer, right click the file name, select Properties, and click “previous version” tab.  The files must be from server sys folder, not from local My Document folder to have the Shadow Copies.

·        Manual offline Backup is done once a month: need to stop mail service first, and then run Backup program.

·        Backup to DVD

 Restore Data:

·        File Server Restore.  Three options are available: from Shadow Copies (6 hours old), or from DCS1 (1 hour old), or from D (1 day old):

·        Main Email Server local restore: Run start/programs/Accessories/system tools/backup. Check restore, and specified restoring from K:/Backup/.

·        Network restore: copy all folders from Recovery server D:/Exchsrvr/

·        Recovery Email Server: Turn off main server,  and remove disk 2 (300GB).  Install Disk 2 to DCS1. Change IP of  EXDCS1 to 192.168.23.2,  and rename computer to EXDCS2. Under Services, select Automatic, and start all Exchange services.

   Disaster Recovery plan:

·        Scenario 1 : Boot disk failed, or file corrupted

·        Resolution 1:  Break disk mirroring. Stop unattended backup program, and stop “idem” which is running on the recovery server.  Switch cable for disk0 and disk1, and remove the bad disk. Insert the bootable SD module.  Change BIOS to boot from E:.  Downtime is about 4 hours.

·        Scenario 2: A file is corrupted. Windows or Exchanger services can not start.

·        Resolution 2:  Stop all backup programs on both servers.  On the main server, boot to recovery mode, if necessary, and copy the file from the backup server, or CD. Minimum loss of data. Downtime is about 1 hour. 

·        Scenario 3: Server hardware, CPU, or main-board failure.

·        Resolution 3: Move disk 2 (K:) from main server to the recovery server. Activate Recovery server (see instruction on Restore section). Restore Storage Store from K: Connect Recover server online to receive mails.   Estimated downtime: 4 hours.

·        Scenario 4: both servers are damaged beyond repair.

·        Resolution 4: Bring the rescue NT server from off-site location. Update user accounts and use in production immediately.  Build new server and restore data folders from the DVD-ROM.  Estimated downtime 4-24 hours.
