On a Macintosh, you can use a tool like BBedit - Free Edition to compare two sets of web pages and move changes from one page to another. (Text Wrangler can do this comparison and its free, BBedit is a paid product from the same company).
If you don't know which file to edit or compare, you can use various methods to find the file |
You can do a comparison on either:
In either case, the approach is:
By copying the pages, you can make changes to the web pages and test them in a test environment.
If you are jumping a few versions, you will need the web pages changes between the current version you are running and the latest release, or you can simply download a full copy of the latest web pages.
Use BBedit - free edition (or similar file comparison tool) to compare all files in a folder.
In the find differences window that opens, put the names of the old and new WebPages folders as per the picture below and click Compare.
This shows you the list of files that are different (bottom left) and under that, the actual differences in the files. Clicking on any one difference will show you where in the file the differences are and you can apply them (or not) in either direction. Repeat this decision making for all files that are different.
