I have installed vBulletin and test converted the forum once. It went so fast and easy, that I’m doing to “real” conversion immediately. There’s some maintenance and fixing I will need to do after, but I should be able to re-open the forum later today or no later than tomorrow.
I’ll post here when it’s all done and ready, or if there’s any problems.
Update:
All’s imported over and working as it should, but there is one thing that needs fixing that the importer couldn’t handle properly. It’s more of a cosmetic thing, but it does make posts that use the feature in question harder to read and uglier, so I’m not opening the forum just yet. I paid someone to get a copy of a custom script they had had made earlier to fix the issue, hopefully I’ll get it soon! I’ll keep you posted.
