The
first part of the solution requires you to prepare your system and your
Active Directory (AD) for the changes that are coming with SP1.
Consider the following: You
need to make sure you meet the minimum requirements, which starts with
making sure you have SP2 installed on the server (one of the
prerequisites).
Begin
the upgrade process with the servers that are your firsts for roles.
It’s recommended that you begin with your Client Access Server (CAS)
and Hub Transport (HT) servers in a larger organization, where your
servers may be broken up into their individual roles.
A
Schema update is required, which you can perform separately or during
the install process. However, in either case you need to be a member of
the Schema and Enterprise Admins group. If you haven’t prepared the
domain, you can do so separately through a command prompt, or you can
do so through the install process, but in both cases, you must be
logged on with a user that is in the Enterprise Admins group.
Make
sure you have the proper permissions to perform the upgrade. On an
internal Exchange server (Hub, Mailbox, CAS or UM), you should use the
account that is delegated the Exchange Organization Administrators role
(if it’s the server that is your first in your organization). You
should also be a Local Administrator on that system.
If you want to upgrade the Edge Transport server, you need to be a member of the local Administrators group for that system.
It’s recommended you stop and restart the Remote Registry service.
Be aware of the following caveats to the process before you attempt to proceed:
If
you are working with a clustered mailbox server, you can perform only
the upgrade through the command line interface (CLI), which we
demonstrate shortly.
Do
not attempt to upgrade your Server 2003 running Exchange 2007 RTM over
to Server 2008 first and then attempt to upgrade from the RTM to SP1.
This can create havoc. Instead, you can uninstall Exchange and then
perform the upgrade to 2008, then reinstall Exchange SP1 (keeping in
mind that RTM doesn’t install on Server 2008). Again, to place SP1 on a
server running 2008, there is no upgrade. It’s a direct install.
Perform
the upgrade using the GUI or the CLI. From the GUI, begin the process
by inserting the DVD or mounting the ISO file you might have. After you
see the introduction Start page from the wizard, perform the following:
1. | Under Install, select Install Microsoft Exchange Server 2007 SP1.
|
2. | Click Next at the Introduction page.
|
3. | Select I Accept for the License Agreement.
|
4. | After
the Readiness Check comes back with green lights saying you have met
the prerequisite checks, you can select the Upgrade option to begin the
upgrade.
|
5. | From the Completion page, select Finish.
|
In the event you will use the CLI, you need to open a command prompt and perform the following:
Make sure the DVD is in the drive or the ISO file you have is mounted and you know the drive letter.
From the command prompt, navigate to the location of the setup.com file.
Then type setup.com /mode:upgrade.
