I already started a thread some time ago here but now me and my partner are really looking to change our forum software from vBulletin to XenForo.
We have a forum with over 1.2 million posts and a few addons installed. I would like to know from someone with a similar sized forum who switched from vb to xenforo if there was any trouble when changing the software, it's a big forum so I don't want to mess with it, it also contains a lot of attachments and images uploaded so I just want to make sure everything will be working just fine and nothing will be lost.
Another thing I am really looking for before moving to XenForo its a xenforo's theme designer. We want to make the switch smooth to our users so we're looking to pay someone to create a custom theme for us based on CompleteVB's "Life.Element" theme, which is the one we are currently using. Here's the link to the theme preview: http://www.completevb.com/product/38
Regarding our current addons, I'm pretty sure we will find some of them in the free section and maybe some not, in that case, is there a paid request section so we can hire a few coders to create addons for us ?
Budget is not a problem for us, we're looking to move ASAP with a theme similar to the one we currently use.
