Login Via SSH to server
and run this command
plesk bin reconfigurator /root/ip_map_file_name
It created the file
Now you open this file and it like this
venet0 192.168.113.2 255.255.255.255 -> venet0 192.168.113.2 255.255.255.255
Now you change your ips and add new IP
venet0 192.168.113.2 255.255.255.255 -> venet0 172.0.113.3 255.255.255.255 and save
and then run
plesk bin reconfigurator /root/ip_map_file_name
It change the ip and run all services related this
Thanks
