Redirecting old domain urls from old host, to new domain urls with new host, but individual pages are named differently

Question

Both domains were purchased through network solutions. The old host won't exist anymore, so I can't rely on them to serve the htaccess redirects. I can point the nameservers to the new host, but then what? None of my redirect code seems to be working. Any help is much appreciated.

Ex: 
olddomain.com > newdomain.com
olddomain.com/hello > newdomain.com/goodbye
olddomain.com/123 > newdomain.com/456

You probably want to do something similar to this: .htaccess RewriteRule: two domains using same server and directory

Having that said, in most cases a static html page saying "This page has moved. Link to new page: ..." is preferred above .htaccess redirects, because people browsing your webpage will then update their bookmarks to the new URL, which they will not otherwise.
