If you have two VPS machines, you can use the panel to migrate all data from one to the other. This assumes you've just added a brand new private server.
- Navigate to the VPS page.
- To the right of the server you wish to delete, click the Delete button.
- You are presented with a page that offers you the option to migrate all data to a different server. In the screenshot above, everything is being migrated to a Shared server.
- Click Move everything on ps### to <newserver> and then destroy ps###!
Your data will begin to migrate to the new private server. This could take some time depending on how much data there is to transfer.
