Is there a simple mapping rule from trac wiki URLs to new gitlab wiki URLs?

I'm trying to update the wiki URLs in the GHC user's guide. However, URL mapping is somewhat difficult.

For instance, I can not simply replace the URL of a view pattern.

• Old trac wiki
  • https://ghc.haskell.org/trac/ghc/wiki/ViewPatterns
• New gitlab wiki
  • https://gitlab.haskell.org/ghc/ghc/wikis/view-patterns

They are different like ViewPatterns and view-patterns. Is there an appropriate solution?
