Upgrading Builder Version
I am going through some old client sites I did and would like to upgrade their version of PowerCMS. I believe I created them with the PowerCMS Builder prior to Super Suite (which I now have). The newer PowerCMS pages give me a variety of options, and to keep things current and similar across the board, I would like to update the other sites, but how do I do that without deleting the content/pages of the existing sites?
I was looking at past forums, and similar questions referred to overwriting certain files, but I don't know what files and how to get them since they are created and automatically added in the extension. I also couldn't find a tutorial on this.
