Golden Software's Surfer and Grapher programs offer two types of licensing: single user and concurrent-use. If you own a single user license and would like to convert that license to a seat in a concurrent-use license, you may do so at a 1:1 trade in ratio with a discounted price. The discount is the value of a current single-user license (Surfer $849 USD; Grapher $489 USD).
To convert your single user licenses:
- Email email@example.com with the list of single user license serial numbers or product keys you wish to convert to seats in a concurrent-use license.
- We will generate an estimate for you to review and approve.
- Submit payment.
- Your order will be processed, and you will receive your concurrent-use license via email.
Once your order is processed, the single user serial numbers used to convert to seats in a concurrent-use license are no longer valid and can no longer be used.
