unless configured to be checked earlier with relect_unlisted_recipient,
relay_recipient_maps is checked at the end of the
smtpd_recipient_restrictions, which happens at the end of the RCPT TO
during the smtp exchange.
Rewriting with generic_maps happen, when the mail leaves the Postfix system.
So, if you want to keep the old domains, you need to change your awk
script to include valid user addresses for the old domains as well.
Just put in a loop to add the extracted user for the old domains as well.

relay_recipient_maps. Though usually the question is "Why doesn't it work
when I put in '@... OK'?"

Do you have a check to reject Mails from outside your network for $myhostname?
