Upgrading from Phil-A-Form 1.2.x to Phil-a-form 1.3 is really easy, as long as you have not modified any of the Phil-a-form core files.

Simply:

• Unpublish the Phil-a-form Mambot
  
• Uninstall the Phil-a-form Mambot
• Uninstall Phil-a-form Component (Dont worry - your forms and data are not removed!)
  
• get new copy of Phil-a-form from http://www.phil-taylor.com/cc
• Install Phil-a-form Component
• Install and publish the Phil-a-form Mambot

There are no database changes :-)
