If you're a new customer and you're considering an upgrade to a VPS from a shared hosting environment (existing shared or reseller hosting plan), we recommend talking to our experienced sales team to help guide you through the migration process and offer some considerations before you make the jump. If you're an existing customer, talk to our support team for assistance. In essence, it boils down to the amount of traffic your website experiences, number of files/storage requirements, business application/software needs, security and isolation from other users. For businesses that require mission-critical access and uptime, VPS and Dedicated Servers offer the ultimate reliabilty and security.
