This software is completely new from the ground up. It is not necessary to convert to Astra and there may be business reasons to stay with Classic for the time being.
There will however be a fee to convert from Classic to Astra when you decide to do so. The fee for current Classic users will be the Astra list price less a discount for every year you were on the Classic support plan. The number of years you have used Classic also comes into the calculation. Please contact our sales desk to receive your exact credit amount available to your park.
