About changing the format of the SOA record's serial number
This feature allows you to change the format of the serial number field used in the Start of Authority (SOA) record for all new DNS zones from an integer to a YYYYMMDDNN format. In this format, YYYY refers to the current year, MM to the current month, DD to the current day of the month, and NN to a 2-digit integer, ranging from 00 to 99.
Note: To change the format of the serial number field used in the SOA record for all existing DNS zones to the YYYYMMDDNN format, after enabling this feature, you must run the editSoa.vbs script included in the Unify DNS 2.4.0 hotfix 2 located on the Ensim Support site. For instructions on running this script, refer the releasenotes.htm file included in the hotfix.
If the YYYYMMDD part of the serial number field in a SOA record of a DNS zone is less than the current date, then the next update to any record of that zone will change the YYYYMMDD part to match the current date, and the NN part will change to 00.
If the YYYYMMDD part of the serial number field in a SOA record of a DNS zone is equal to the current date, and the NN part is equal to 99, then the next update to any record of that zone will change the YYYYMMDD part to match the date for the next day, and the NN part will change to 00. This record update operation will also log a warning message on the Action Log page about this update to the serial number field.
