Objective

Preserve search continuity where it truly matters, without attempting to replicate the entire historical URL structure of the old site.

Context

There is a limited number of pages in the search index—around 85. Therefore, full backward compatibility with all legacy routes is not required.

What to do

• Collect the actual list of indexed and other truly significant public URLs.
• For each URL, determine the target page in the new haih-cms structure.
• Where reasonable, keep the address unchanged.
• For changed addresses, prepare targeted permanent 301 redirects.
• For outdated pages without a useful equivalent, make an explicit decision: merge with a new page or return a correct 404/410 depending on the situation.
• Exclude redirect chains and loops.
• Verify the consistency of the new URL map with canonical tags and sitemap.

Result

A small, manageable SEO migration map for truly significant URLs instead of maintaining all legacy routing.

Definition of Done

• All indexed and significant URLs have been resolved.
• Direct 301 redirects are configured for the necessary pages.
• There is no requirement to support the old Rails routing entirely.
• The new URL structure is considered primary and canonical.
