What happens to apps left on device when unenrolling (BYOD)?

[jriker]

We have a scenario I wasn't expecting.  So basically we are eliminating JAMF and going with InTune.  Know not a new story.  However as this was never expected, all BYO devices have "our" apps set to remove on unenroll and were installed thru VPP.  This is going to cause a lot of issues as the individuals aren't leaving but being asked to unenroll and then enroll in a different MDM.  If we set the apps to not uninstall when unenroll, what would happen?  So the apps I guess stay behind but...

1. Will they keep working?

2. If they keep working will they stop eventually?

3. Will they be able to get app updates?

4. Will the apps magically get tied to their own iTunes account?

5. Depending on above, if a user goes into their Apple App Store and installs the app while already on the device what will happen?

Thanks.

If you set the apps to not uninstall on unenrollment, they will likely stay on the device but may stop receiving updates or lose licensing since they were deployed via VPP. Users might need to reinstall them via the App Store to regain full functionality under their own Apple ID.
