Alex: I have been holding off on migrating from 2.3.5 pro to 3.0.8 simply becasue of the required re-design of my currently customized templates. Is there any hint as to how I can convert the data from my old templates to new templates? Can I edit the new templates safely in Dreamweaver? That's how I modified the old ones.
There are no ways to convert it automatically. Templates needs to be customized again http://manual.amember.com/Templates_Customization
