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 VPS.
- Navigate to the VPS page.
- To the right of the server you wish to delete, click the Delete button.
- A page opens that provides you with the option to migrate all data to a different server.
- Click Move everything on ps### to <newserver> and then destroy ps###!. This ensures your data is copied to the new server where you'll continue to host your site.
Your data will begin to migrate to the new VPS. This could take some time, depending on how much data there is to transfer.
