Usually any ticket, expect one that shares revenue with other parks and / or entitlements (i.e. 3-Park Unlimited, Orlando Flex Ticket, Orlando Flex Ticket Plus, Park-to-Park with Unlimited Express Pass) can be upgraded to an Annual Pass. Typically, Guest Services in-person, will scan the ticket to determine the value of the ticket paid through your employer. Then, you'll pay the difference between the desired pass type and the value of your ticket. For example, if you bought a 2-Day Park-to-Park ticket through work for $175.99 and want to upgrade to the 2-Park Preferred Pass, which is $299.99, you'll pay $124.00 + tax. You can reach out to Guest Services on the phone at (407) 224-4233 for additional information. Do again, please keep in mind that upgrades have to be done in-person at any ticket, pass or Guest Services window at the parks and cannot be done via phone.
