Converting Zone Files Between Text and Raw Formats

With the development of the BIND 9.9 branch, zone file storage for slaved zones has been changed to expect the raw zone format by default.  BIND administrators testing 9.9 or preparing for migration from an earlier version have asked how to deal with this format change.  Several options are available.

Rename and Retransfer:  A BIND 9.9 slave server which encounters a zone file it cannot read (for example, because the contents are stored in a format other than what the server expects) will rename the unreadable zone file and attempt to retransfer the zone from the master.

Manual Conversion:  The named-compilezone utility, which is part of the BIND distribution, can be used to convert zones from text to raw and from raw to text.

# convert raw zone file "", containing data for zone, to text-format zone file ""
named-compilezone -f raw -F text -o

# convert text format zone file "", containing data for zone, to raw zone file ""
named-compilezone -f text -F raw -o

    The configuration option "masterfile-format" (which is documented in the Administrator's Reference Manual) allows you to specify what format the zone data is stored in.

    You can use the usual scoping mechanisms to apply the value globally or on a zone-by-zone basis.

    [ tuserpe]: Keeping zone files in text format 2013-04-05 05:45

    How can I configure bind9.9 to keep using the text format for zone files? I need to upgrade to bind9.9 but I have more than 2700 zones files in 4 different views and the zones have been set up to include different files for the different views. I prefer my current set up.
