We're upgrading from CF 7 to CF 8 and I'm looking for an Adobe document saying
what programmers need to look for to make the code still work (i.e. new
reserved words or changes in functions). All I'm finding is documents talking
about the new stuff. That's all good for upgrading the site, but I want to make
sure what I have now works.

For example, a few years ago after an upgrade from one CF version to a new
one, we discovered a page broked because all of a sudden "version" was a
reserved word, so we had to rename the variable.... stuff like that. While we
plan to test our full site in CF 8 on our development server before installing
it on the production server, a guideline on what to look for in the code would
be great.

Hi,

Use the "Code Analyzer" link available under the "Debugging and Logging
Section", it evaluates the incompatiabilities between CF8 and the previous
versions..
