Hi there! I've been looking into switching to a different forum software for quite a while now. I currently run a forum that uses PHPbb 3.0.11 and I'm trying to convince our webmaster to switch over to Xenforo. PHPbb is alright but it feels very outdated and has a clumsy design. Many of our users have also found that it's riddled with bugs and isn't very open to develop. A little about our current setup: 66,000+ users 358,000+ posts 2.18GB database PHPbb 3.0.11 Why I want to switch - will Xenforo help me here? Interface looks dated (I know this can be updated but our needs are very particular and PHPbb doesn't really cater to what we're looking for) User control panels aren't intuitive enough for our users, who are mostly 40+ Admin control panel is clunky and unresponsive My main questions Will we lose any of our SEO ranking during/after switching to Xenforo? Would our users be inconvenienced in any way? (Forced password changes, profile changes etc.) Are we able to set the software up using IIS? Does the forum software have any spam countermeasures? Will our current IP, e-mail and username bans be carried across? Will post attachments be carried across? Will it be simple to set up our custom TapaTalk app with Xenforo? Thanks in advance for any answers you can provide.
