We've been using 13.0.2 for a long time, and have invested a lot of time getting everything to work correctly. It's old, but it works for us so until now we haven't really felt the need to upgrade to a newer SP. However, because of this issue we're now thinking about updating, and we might as well go to the latest version.
I'd like to install SP13 to try it out, but if it ends up breaking a lot of our existing code we may just decide to tough it out and stick with 13.0.2. When I install SP13, will it replace my existing SP2 installation, or will I be able to uninstall it and automatically be back to SP2?
