Golden Software's Strater, Surfer and Grapher perpetual programs offer two types of licensing: single user and concurrent use. If you own a perpetual single-user license and would like to convert that license to a seat in a perpetual 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 (all pricing can be found here).

To convert your single user licenses: 

1. Email sales@goldensoftware.com with the list of single user license serial numbers or product keys you wish to convert to seats in a concurrent-use license. 
2. We will generate an estimate for you to review and approve. 
3. Submit payment. 
4. 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Once your order is processed, the single user serial numbers used to convert to seats in a concurrent use license are no longer valid and can no longer be used. 

If you have a subscription license of Surfer or Grapher and are interested in converting your single-user subscription to a concurrent use subscription, please see: Can I convert my single-user subscription to a concurrent subscription?
