User blog comment:Devilmanozzy/When is a good idea to start a new Wiki?/@comment-26686429-20110507223000

I'd agree with this, often it's a case of asking yourself "is this wiki in such a mess that starting a new one will be more hassle than adopting it". Also consider the URL of the wiki, if a lot of people are going to be going to topic.wikia.com - but your wiki is at topicwiki.wikia.com - you might lose some people, that might be a good reason to stick with the old wiki. If you're starting a new wiki, you can always use Special:Export and Special:Import to bring some of the good articles from one to another.
