Correct, one should not have multiple "alternative" URL modules installed. One could leave the Ultimate URLs .htaccess in place (before the CEON rules), but doing so will probably cause unneccessary redirects. As part of switching - One would want to enter the old (Ultimate) URLs into the CEON URI database.

Actually both Ultimate URLs and FEC can operate together. I've posted on this topic before and Diva is one of the contributors who helped narrow down the issue (caused by Numinix altering the default Zen Cart administrative configuration flow - and - Ultimate URLs depending on the stock Zen Cart administrative page for managing configuration options). They are not incompatible with the appropriate patches to the Numinex code installed.

Any further discussion on the topic of Ultimate URLs and Numinix modifications to the Zen Cart administrative configuration process does not belong in the CEON URI thread, but over at the Ultimate URLs (or FEC) support threads.
