Hello-
I have SQL 2000 x32 Standard installed on a X64 Win2K3 server. I'm trying to
upgrade to SQL 2008 Standard. Both the Sys Config & Upgrade Advisor tools say
I'm cleared for take off. However, when I try to upgrade, I get "there are no
features selected for upgrade" under Select Features and I can't go any
further.
This is a first attempt and there are no previous bad or partial SQL 2K8
installs on this box.
Is this happening because I'm attempting a cross-platform upgrade (X32 to
X64)? If so and I can't do that, what is the best way to accomplish this
upgrade?
Thanks

Yes, there is no upgrade path between x86 and x64.

One way is to install SQL 2008 as a named instance on the machine. You can
then keep the SQL 2000 instance, and copy the databases with backup/restore
to the SQL 2008. The advantage with this is that you can keep SQL 2000 as a
reference, in case you have query that starts to perform badly on SQL 2008.
(By the way, make sure that you update statistics when you migrate the
database to SQL 2008, as all statistics are invalidated.)

The drawback is that all clients will need to change so that they connect
to the new server. You will also have to migrate logins and Agent jobs.

The other option is to uninstall SQL 2000, and install SQL 2008 and
reattach the user databases. Make sure to take a backup of master and
msdb before you uninstall. You may be able to restore this on the
new instance, but I have not tried this. If that works out, logins and
jobs are automatically transferred.

Yet an option is to find completely new hardware, and install SQL 2008
on that hardware, and the rename the machines, so clients does not have
to change.

I'll just go with the new hardware option..Thanks for your help.
