2000 to 2007 Upgrade Help

I am finalizing an Office 2007 deployment and am running in to one
last snag. We are currently running a Windows XP environment with
Office 2000, and the Office 2007 upgrade/installation does not bring
current user settings and macros with it. I have used the /admin on
the setup to create the MSP file, and did select Migrate User
Settings, but like I said, nothing is migrated.

I did test whether the 2000 to 2007 update itself was the issue and
have manually created an OPS file and tried importing it to 2007,
which said it was applied, but no settings were changed. I have also
tried taking steps going from 2000 to 2003, then to 2007 and the OPS
file does the same thing from 2000 to 2003, so I didn't try taking
things to 2007.

I have a number of users that use many different macros and have
highly customized environments, and really need a way to upgrade them
to Office 2007 while maintaining as many of these as possible, does
anyone have any suggestions how to do this?

Thanks.
