We are using flowable 6.4.2 currently. We want to move to 6.6 version
Therefore, we followed the staggered approach on our sandbox system to first upgrade it to 6.5 and then later from 6.5 to 6.6.
After performing an upgrade from version 6.5 to 6.6, we lost all the apps created in flowable. Do we need to export all the apps before upgrade and later import them? or there exists some other way of retaining the apps post upgrade.
Is this a normal behaviour? or did we miss some pre-requisite towards the upgrade?
