Upgrading from Exchange 2K Ent edition to Exchange 2K3 Ent edition

Currently I have Exchange 2KEnt and Veritas BU Exec running on the same
overutilized/under spec'd box. I am in the process of buying a new server
and will be installing 2003 server Ent. edition and will be purchasing
Exhange 2003 Ent edition to install. I will need to migrate the Exchange 2K
data over to the 2K3 box. The existing box is also a DHCP Server, DC,
alternate DNS and a GC.

What is the best migration path to take?

There are three other 2K DCs on the domain as well. The plan is to upgrade
those to 2K3 standard.

Your help is greatly appriciated.

 

Hello Tina,

Good to hear from you.

According to the message, I understand that you want to migrate to
Exchange2k3 environment and upgrade the existing win2k DCs to win2k3. Is
this correct?

Please understand that this newsgroup mainly focus on the migration of the
Windows part. As for the Exchange part, I would like to suggest that you
post in the microsoft.public.exchange.setup newsgroup since they are the
experts in Exchange and will provide the most accurate information on this
issue.

As for the Windows part, since you want to in-place upgrade the existing
win2k DCs, the process is as follows:

1. Perform a full backup before you take any action.

2. Run "ADPREP /FORESTPREP" and "ADPREP /DOMAINPREP" to upgrade the
existing Windows 2000 forest and domain to ensure that they contain the
additional objects, attributes and permissions necessary to support the
Windows Server 2003 Active Directory environment.

3. Perform an in-place upgrade.

Please refer to the following article for more information.

In addition, I would like to suggest that you perform Exchange migration
first. Please do not install Exchange2k3 on a DC, this will bring up
certain issues.
