We had a physical server with a Plesk container on it and the server failed recently. Plesk node was brought back up in a Virtuozzo Container and PBA-S still shows Plesk node as registered in broken server.
How to change the Plesk container properties ?
Change the properties usual way: click Edit and choose Virtuozzo node and put proper container ID. Then click "Synchronize" to synchronize Plesk Clients and Domain with PBA-S.
