The best practice here is to try to avoid rewriting URLs if at all possible when changing platforms/CMS systems.

No. As jdmorgan said above, a rewrite would be a much better thing to use, instead of a redirect. With the rewrite in place, you would continue to use the same URLs 'out on the web' to access the content, even though the internals on the server are completely different.

I have a site that continues to use .asp URLs even though the site migrated to Apache hosting and PHP scripting many years ago.
