AHVLA now APHA: changes needed to AHVLA and Defra

Users can no longer access AHVLA mappings, as they are now part of 
the new APHA organisation.  PR changes site ownership to new 
organisation and makes Defra mappings available to that new 
organisation.
Would it do any harm to include both organisations? Then the site can be found under the new or old organisation.

If so, we should do the same for the site below.
