Apps are "unmigrated" after upgrade

[Lauri]

Should I be concerned that all of my apps have a migration status of "unmigrated" in the QMC after upgrading to September 2019? The apps work, so I'm not seeing any immediate problems. 

Seems like the documentation in the Help isn't up-to-date on this topic.  This page doesn't even mention the "Migration status" column that I see in the QMC. And it mentions "Version," a column that I don't see.

Good morning @Lauri,

This is the new behavior from September 2019 forward. Take a look here: https://help.qlik.com/en-US/sense-admin/September2019/Subsystems/DeployAdministerQSE/Content/Sense_D...

Hope this helps, 
Riccardo

Thanks, Riccardo, that's helpful. So I should highlight all of my apps and click "Migrate" in the QMC? Any known risks?

You're correct @Lauri , you can proceed manually.

I'm not sure why Qlik did this change, my guess is that now it is manual in order to not overload the server with too many requests/apps too big (at least in big environments).
So personally I would migrate the apps in groups, however I'm not aware of any known limitation/risk.
