Some years back I installed 5.45c for a friend. No problems, easy set up.
Now she wants to upgrade to the latest version. I've done that on my own sites before, but it's been awhile since I messed with 5.x versions. I've got the 5.x > 6.x upgrade info, but I have a few questions.
Mainly, am I going to have problems with the size of her forums? 21,000+ members. One category with 8894 topics and 18778 posts, another with 5125 topics and 23581 posts. Those are the high end, but there are a few more that approach that.
And should I upgrade to 5.47e first, or can I go straight from this version?
