Every Shared Account can be easily fully migrated to a Hepsia based VPS Server where no actions nor changes are needed from you.
What needs to be done is just to order the new Hepsia VPS Server and contact us back with the Username of the Shared Hosting Account you need migrated to it (make sure that the VPS plan allows that much Disk Space).
Shared hosting plan can be easily upgraded to VPS or Dedicated Server, if you want. However, you will have to contact your hosting provider to migrate from shared servers to Private server. I use shred hosting, and have never felt a necessity to upgrade to VPS.
