What are the kind of challenges faced when we migrate/move from versions of ATG commerce (<10) that were not using EndecaExp Manager to versions that use it. For ex, would all the JSPs undergo a change in the way they are rendered, given that the pages will now have to be template driven ?
What would be some best practices here to have a minimum impact of the move on the UI & maximize the reuse of the JSPs ?
I have read the migration docs but they do not seem to cover this aspect.
