reasigning A-numbers looks like a bad idea.
Leaving the entry as is looks bad too : it can clutter the true hits..
Maybe just :

%N A019505 Same as A006753.

with a link (without back-link) to the target,
and a warning message asking to update that link.

But I would keep such a minimal reference (as above) for eternity.
