Pages and Posts No Longer Work after Migration

I have migrated my site and pointed my domain to it. The home page works just fine but all of my sub-directory pages and posts are giving me a 404 Not Found Error. I want to get everything working on this domain before I point my actual intended domain to this site. I assume whatever exercise I do to fix it I will have to do again when I change the domain again and I am assuming I need to do some sort of DB replacement. Any help would be appreciated
