There are lots of subscriptions assigned to an IP address in Parallels Plesk for Windows. How to switch those subscriptions to a different IP address?
Note: for Linux refer to this KB
This can be accomplished using Parallels Plesk Reconfigurator:
Log in to the Panel-managed server as a user with administrator rights by using Remote Desktop.
In the Windows Start menu, select All Programs > Parallels > Panel > PP Reconfigurator. The Reconfigurator application window opens.
Select the Change server IP addresses option. The IP Addresses Reconfiguring window opens.
Under Select the IP addresses to be changed, select the checkboxes corresponding to the IP addresses that you want to change to other IP addresses.
To view the list of domains hosted on particular IP address, click the IP address entry to highlight it. The list of hosted domains using the highlighted IP address is displayed in a window to the right.
Map each selected to an IP address of your choice.
5.1. To map a selected address, click on the selected address entry. The entry is highlighted.
5.2. Select the address to map to:
To map to an existing IP address, select Existing Address option and then select an existing address entry. The entry information is displayed in the Mapping Information column for the selected IP address entry under Select the IP addresses to be changed.
- To map to a new IP address that will be created during mapping, select Create New IP address option and then enter the IP address, network mask, and network interface name. The entry information is displayed in the Mapping Information column for the selected IP address entry under Select the IP addresses to be changed.
Panel installation is reconfigured to use the newly specified IP addresses in place of the old ones. All relevant records in the Panel's database are updated, network adapters settings are changed accordingly (the old IP addresses are removed), FTP and web servers are reconfigured accordingly, DNS records are updated accordingly.
Note: If changing IP address fails during execution, all changes are rolled back. When connected to the server through the Remote Desktop connection, a change of your server’s IP address will terminate your session.
