Another option (if your zone is dynamic) is to use nsdiff, which generates
an nsupdate script based on the differences betwen zones. You can use it
to automatically copy changes from the main version of your zone to the
special VPN version. The tricky bit is writing a regular expression to
tell nsdiff to ignore changes to the Lync records.

Something like:

dig -k standard-view-key +noadditional esri.com axfr >db.esri
nsdiff -k vpn-view-key -i '^(_sip|lync)' esri.com db.esri | nsupdate

That regex is very sketchy so you will need to turn it into something more
precise.
