Quite a few things have gone bottom up, most of which I can either work around or don't affect me personally. There are two other ladies that update this site, however (I'm mostly their techy and web designer), and they are having troubles. One of them in particular as I mentioned in another thread, is having IE crash completely when she does a certain thing.
It seems the cms_selflink WYSIWYG button is working completely differently between these two versions and now gives me utter crap for output. I had to go and completely re-set all my TinyMCE stuff so it would work again. And various other small things have happened, but we can deal with most of them.
So my question here is, what would be the best way to upgrade? (Yes, I backed everything up first.). I considered going step-by-step through the diff and new version files, but that seemed illogical after reading a post here that mentioned that each new version will upgrade all old ones (or some wording to that effect).
Now I'm wondering if I should have maybe started at the minimum with Ver. 1.3 and tested, then gone on to the next one, tested, etc.
Is there any point to that? Or was I right to do what I did? I think as long as we can fix the IE crashing problem, we could work without the cms_selflink button and a couple of other inconveniences we can work around. But at this point, my ladies are begging me to go back to the old version - which I keep reading would be a virtual sin to do.

Any advice on upgrading procedure would be very awesome.
