Content should be unaffected by the migration, though some tags no longer work. Can you elaborate how it's messed up? It might be a known issue or something that's got a simple fix.

Blockbuster and Toys' R' Us failed because they failed to adapt to a changing market and could no longer keep up with the competition. If you want to use them as an analogy, it's what would happen if Fandom were to keep Legacy.
