What was your upgrade experience?

[Reeve of shinra]

3.8.5 works and works well... if your comfortable where you are at, then maybe you should hang out until 4.1 is released.

The template system hasn't changed much so that part is good.

The new stylevar system is a nightmare and I hate touching it. ITs complex, ugly to look at, needless complex, and its easier to find a needle in a haystack than the var you need to make a simple color change happen. If all you are changing is the header / footer, that shouldn't be too bad. For the rest, just find a design you like for 4.x and use that.

Mods -- didn't have too much issue finding the ones I want. Thankfully some of the 3.x mods still work.

Seo -- you can leave the url structure alone for now. I like the friendly urls and feel they help a bit myself.

Bigger question:

Are you going to switch from wordpress to the vb cms? That's another ballgame entirely and right now, I think wordpress is far better.
