Plesk (according their documentation) does not support the transfer of serverwide settings as part of their migration module.
As the Plesk (as far as I understand it) maintains their own database of firewall settings, from which an iptables-procedre is generated, the following transfer procedures also fail:
iptables-save / iptables-restore
- copy of the iptables generating file
Simply as they are all overwritten by the next generation process.
So my question:
Has anyone a practical solution (proposal) how to efficiently transfer the firewall-settings from an old to a new system
Environment: Debian 9 to 11 Plesk: Obsidian 18 (both)
