Most IT shops would install a test version of xl2007 and then test their
applications in that environment before making any decisions on upgrading.
Obviously you would want to test the compatibility of moving a file/app back
and forth as well.

the first article should be interesting, but don't stop there.

I'm considering upgrading some of my machines to Office 2007, I have
2002 and 2003 running on other machines.

My main concern is regarding compatibility of my custom apps. I don't
merely mean binding the right object library, I mean Office 2007 is
supposedly a radical reinvention of Office (if you believe the hype)
and perhaps a lot of the methods which worked for the older versions
might not have parallels at all in the new one.

I'm not expecting someone to write me a treatise on the subject from
this newsgroup, but would appreciate pointers to some good web
resources that discuss this issue.

Thanks
