Hi Chris,
this usually happens when the Joomla version is too old. Which version are you using?

Best regards,
Luigi

Hi Chris,
you need to create one or few ReDJ rules. Each rule has a field "From URL" which is a regular expression and can also match partial URLs. So a single rule can match and redirect many URLs. The destination is build dinamically, using {macros}, so a single rule can redirect many-to-many URLs. More information here:

All you need to start is to identify "common patterns" among your 200 URLs. I could help you if you need, but you should provide more information about your URLs.

Kind regards,
Luigi
