Will a 4.4.3 skin work in 4.4.4?
 

I'm making another website that's going to be identical in appearance to a 4.4.3 site I've already built and customized. I'd like to install 4.4.4 and just copy over the skin and be done with it.

I customized the 3-column skin

Am I going to have issues?

I don't think it will but you might have to do some modifications...

It all depends what and how many of the 4.4.3 files you customised to make the skin - but the chances are that it should actually work ok.
What you may want to do, is get hold of the upgrade files for .3 to .4 and see which of your customised files have been upgraded and then decide if you want to upgrade those files too.
