Changing DNS Zone Serial Number Format

RIPE recommends using YYYYMMDDNN format, where YYYY is year (four digits), MM is month (two digits), DD is day of month (two digits) and nn is version per day (two digits).

To change DNS zone serial number format:

1. Connect to the Plesk database (psa).
2. Run the following inquiry:

   insert into misc(param, val) values('SOA_SERIAL_MODE', 'YYYYMMDDnn')

To revert back to old DNS zone serial number format:

1. Connect to the Plesk database (psa).
2. Run the following inquiry:

   delete from misc where param='SOA_SERIAL_MODE'
