Resolved How to change DNS zone serial number?

[klowet]

Server operating system version

Debian 12

Plesk version and microupdate number

18.0.57 #2

Hi

I should have to upgrade the serial number of a DNS zone manually.
How can I do this in Plesk?

Situation: a migration from another server where the zone has a higher serial number (luckily it has format yyyymmddnn).

Thank you

Hi,

Probably, it is not the most technical solution, but I think the most simplest
Create and remove some temporary record in the zone, this action will update the serial on Plesk to the current date. Or do you have to use some date from the future?

That's indeed an option, but quite intensive for +30 domains.

Or do you have to use some date from the future?

No future dates, but a higher serial number (in the two last digits) at the end.

Is there an (CLI) option to increase the serial number of the zone files? I should manually edit the zone file, but that won't work.

All available CLI commands for DNS record management - dns: DNS Zones on Domains. Unfortunately, there is no single command to set specific Serial for the zone. I do not recommend to modify zone files directly. As an option, you can change format to "timestamp" and back to "yyyymmddnn", it will generate new Serial with actual date.
