does the legacy code take up a lot of space or something? not sure I understand rush to remove, some kinda copyright issue?

re Nguyen comment on finding old communities: one thing I noticed sometimes is the old .wikia addresses work to redirect but equiv .fandom redirects do not.

For an easy example:
 * wwe.wikia.com
 * wwe.fandom.com

Only the former redirects to prowrestling.fandom

It looks like in the move only prowrestling.wikia was redirected there but they neglected to also redirect what the old redirects would be if they were also moved.

Is that feasible to do en masse?
