What is the best method to upgrade from jQuery 1.7? Should I do it incrementally (i.e., from 1.7 to 1.8, from 1.8 to 1.9, etc.) or upgrade to the latest version in one step?
It completely depends upon what you are upgrading as to what you should do (i.e. is it a mission critical site or your personal blog etc).
How bad is it if things go a little pear shaped?
You should also decide which branch to install - currently there is 1.x and 2.x.
One main difference between the two is that 2.x drops support for IE 6,7,8
Also, here is a good article on some of the new 2.x features: http://www.sitepoint.com/whats-new-in-jquery-2-0/
Hope that helps.
Let us know if you run into any difficulties.
Thx Pullo. That's great information. I appreciate it!
