Huh?  That zone file should just contain an entry for "localhost":

1.0.0.127.in-addr.arpa.  PTR  localhost.

Nothing about your domain needs to be in there, and it doesn't need to be
changed as you migrate from currdomain.com to newdomain.com.

You do.

Since the IP address isn't changing, the name doesn't really matter.  All
that matters is that other servers can follow the chain from the NS records
of the domains to the IP address of the server.
