I found a solution. The old domain is embeded in RichText body, so it must be replaced by the new one, running this from rails console:

ActionText::RichText.where("body like '%https://olddomain%'").each do |t|
  t.update body: t.body.gsub('https://oldomain', 'https://newdomain.com')
end

I'm having the same problem. @AndrewBroad, did you find a solution?
