Hi, I've been in the vBulletin camp for quite some time but vBulletin 4 is showing it's age on a site I work on, it's not fast as it used to be, there's compatibility issues, etc. So I'm looking to migrate the board over to XenForo but I have a few questions I'd like to ask. I apologise if some of these questions sound silly but not everyone that I work with is as convinced as I am, that XenForo is the way to go. The board has around close to 6 million posts and heavily uses attachments. If we were to migrate, would it be possible to retain these and not lose them or anything like that? This would be crucial. We use a ton of custom modifications but most of these features are either built in to XenForo or modifications are available in the Resource Manager. One thing is that we also have vBSEO running on it too. What would the best way of overcoming that be? Some of the people I work with are obsessed with it so naturally they'll not want that to mess up. We also rely heavily on iTrader. Is there some sort of alternative for XenForo or is that something we'll need to code up? We use DigitalPoint's Sphinx Search add-on. I'm assuming ElasticSearch would be just as good? I've seen quite a few importers around and I was wondering which would be the best way to go for me? I apologise if this is in the wrong section. Any guidance would be appreciated. Hopefully we can get some good answers and thus convince the others that this is the right way to go.
