Migrating From Microsoft Exchange 2003 to Microsoft Exchange 2007

Migrating From Microsoft Exchange 2003 to Microsoft Exchange 2007

Author: Sharath Reddy

Sometimes, organizations need their servers to migrate to Microsoft Exchange 2007 from Microsoft Exchange 2003, as there are several updated features along with a more efficient way of handling resources. This migration procedure may be simple or complicated depending on the existing configuration of the server. The process of migration requires several steps like defining roles and responsibilities, test environments and setting up hardware for the server.

• The first step is to remove the existing Exchange server. But as the migration process takes some time, all the processes being carried out by it cannot be put to halt. So it is required to designate some of these services to a temporary server, which would act as the primary server during the transition period.

• Complete removal of Exchange 2003 is essential to successfully set up the 2007 server on the same system. The uninstalling process can be carried out in a few steps like disconnecting the existing clients, and transferring their mail server to the temporary server. All the running services need to be stopped before continuing with the removal process. Server objects need to be deleted from the administrator profile.

• Successful removal of Exchange 2003 requires it to be removed from the active directory. The default installation program will remove some of the attributes, but the rest needs to be removed manually.

Another important aspect is the removal of registry keys, as a new installation will not work if those registry values are present in the system.

• Next, the Exchange 2007 installable is used to start the fresh installation in the system. Checking compatibility issues prior to installing is required, which means checking whether the minimum hardware requirements are met by your system or not, differences in 32-bit and 64-bit versions, and so on. While installing, the IP settings need to be configured, by allowing static IP in IPv4, and static or automatic DHCP enabled IP for the IPv6. It is essential for IPv6 to be kept turned on while installing as it will be required to start some of the Exchange services.

• The active directory needs to be set up and configured properly. Specific domain names for the mail server need to be specified, and it needs to be updated to its latest version. A gateway and firewall needs to be installed to connect to the internet. Finally, all the original services are transferred back to the new Exchange server from the temporary server.
Sometimes a trial migration from Exchange 2003 to 2007 version is preferred as a form of simulation in the existing environment. This will help in detecting any kind of issues that might arise during an actual migration, and will help to overcome them.
