Hi,

I'm a first time user of Kentico. I've been tasked with updating the front end and some of the structure of an old Kentico site.
I've managed to update the site from 5.5 to 7 without much of a problem, but the site is built on ASPX, rather than the portal engine.
I'd like to convert the site over to portal engine templates, but I haven't found any information about where to start with this.
Having spoken to kentico technical support they said that I should start converting the pages on CMS Desk > Content, starting with the master page (which is guess is the 'root' page in the list on the left hand side?).

I've gone to Properties > Template to try and change to a portal template, but I can only seem to see one folder. I think this is the one that contains the ASPX files, these are the only templates I am allowed to use.
My question is, do I need to convert the site over to a portal approach somewhere, if so, where?

Just a few hints to get me started should be enough. I feel a little bit lost at the moment...

Thanks in advance for any help!
