Greetings all. I just upgraded to App Volumes 4 with co-exist. I have used the handy dandy application migration tool to bring over my 2.x apps to the 4 environment. Now I have to handle the entitlements of the 4 app stacks and this is proving to be very time consuming using just the GUI interface. Is there any way I can export a list of assigned users from 2.x app stack and import that same list of users into the migrated 4 app stack? I hate doing things manually. HA.
Short version of the answer, no you can't.
I would also suggest not using the migration tool as Appstacks are build totally differently in Appvolumes 4. I know it is an option but we have some bad experience with it in regards to stability and performance. Also, in 2.x you bundled applications for a better performance while logging in, in 4.x you want to have an appstack for every single application.
You should be able to use App Volumes Entitlement Sync - Fling.
I have worked with this product mostly with 4.x, but try it and let me know if you have problems.
As @Ray_handels mentioned, once you migrate the app-stacks to the 4.x environment, I would work on converting them to 4.x packages to leverage the features of AVM 4.x now and in the future.
