The upgrade page gpsoft.com.au/DScripts/upgrade.asp is not exactly transparent to aspiring DO buyers, and I'd like to know what I'm getting into if I buy it and then will want to upgrade to each new version.
So how much AUD is an upgrade to the current version?
Is upgrading to the next version as expensive as skipping versions?
If you enter your details into the upgrade form, it will quote you a cost before anything else happens. You can choose to back out then without being charged anything or losing the ability to buy an upgrade at a later date if you change your mind.
You can also email the sales address if you need more detail or don't want to fill out the details to find out: gpsoft.com.au/footer/contact.html
