There are 3 kind of licenses
The one I'm using is the "Pro". The difference between "Pro" and "Pro 5" is just the lifetime. The "Pro" version is billed by year so you will receive all update. The "Pro 5" never end, but you have to pay just an extra in order to upgrade from one release to another one.
|Pro and Pro 5, are the same|
The Pro version is without limit, so I can test all features of the software. You can use Dataedo for free, but it has limited functionality. Anyway you can download and try the "Pro" version for free for 30-days.
|Lite version and 30-day free Pro|
|The trial form|
Also, there is an Upgrade section
