Ever since our upgrade from 7.0.3 to 8.0.0, we have been having multiple issues, especially with the GWIA.

We've come to far to roll anything back to 7.0.3 so I'm thinking about applying the HP1 patch at least to the MTA and GWIA.

What I'd like to know is... does the HP1 patch do anything to the databases or is it simply an NLM upgrade. In other words, if I backup my existing sys:system folder to save the existing 8.0.0 NLMs and support files, and I install HP1 and it makes things worse, can I just copy the original 8.0.0 folder back and be OK?
