I've got a noob question about upgrading. I run WP on two sites - I'm a long time Movable Type person, but for these two sites, WP handled my needs better.
Anyway, since I'm relatively new, I've yet to have any first hand knowledge of the upgrade procedure. I know you do the standard things - sql dump, backup of website, that's common.
But I did some strange CSS changes, so what I'm worried about is this. If I upgrade to the newest code, how will my custom css (which was tacked onto (and inside) the end of one of the files) be handled? I don't want it to be overwritten.
Also, if I backup the css file, then copy it back after the upgrade (assuming it is overwritten), won't that break something new?
Sorry for the dumb questions, but I'd like to be prepared before I upgrade. Tkx.
