Just a friendly reminder to folks. In order to see the upgrade options available to users who have DttG 2, make sure you have run the latest DttG 2 (v2.7.9 as of this post) at least once prior to your first launch of DttG 3. Otherwise, the upgrade options won’t be presented.
That is correct. In the case of an upgrade, DEVONthink To Go 3 will detect the 2.x installation to offer the appropriate pricing options.
