How do I Redirect Tags from Old Joomla Site to New WordPress Site?

by

This is more an Apache/htaccess question and better suited on Stackoverflow but for the sake of answering try this:

RewriteEngine On
RewriteBase /
RewriteRule ^(components/tag|tags)/(.+?)\.html$ http://example.com/tag/$2/ [R=301,L]

Place it before the WordPress rules in your .htaccess (or Apache conf if you have access).
