Moving from sh404sef and Mosets Tree

i am using acesef 1.3.4 joomla 1.5.15 php 5.2.12 mysql 5.0.90-community-log

I am a newbie and have been using acesef for a day or two - i have been using sh404sef probably since they started and i just want to say i LOVE LOVE LOVE acesef modular approach!!!

Now, with sef urls in mosets with sh404sef it displays a /View-details at the end of the url but in acesef it does not(i like that) but most of my pages is indexed and i will get lots of 404 if i just uninstall and install acesef.  How do i do this...?
