Migrate WordPress Site into Craft CMS. How deal with 404's? I migrate my WordPress site into Craft CMS. So far so good. 
But the URLs for most of the Blog Entries are complete new. What's the best way to handle that? My site is good linked on Google and there are a lot of backlinks. It would be nice to have a solution where I can see which pages the Users call and if it a 404. Afterwards I can create rewrite rules for this sites. 

Finest way was a Plugin that combine this two features. 
Maybe anyone knows one.
David,

I like using Reroute. It's a Craft plugin that lets you create 301s and 302s to any of your entry pages within Craft.
