It seems to take Fantastico way too long to adopt new Wordpress upgrades. I noticed that the new SimpleScripts that is offered now on Bluehost already have Wordpress 2.5 and many other regularly released applications.

I'd like to replace my Fantastico Wordpress installation with a SimpleScripts one, but not loose my site in the process. Meaning, I'd basically like to detach from Fantastico, and re-attach to SimpleScripts so I can do upgrades from SimpleScript.

Is this possible?
