IHubOpenAppAsyncT Method (AsyncHandle, FuncResponse, T, String, String, String, String, Boolean)

Opens an app and checks if the app needs to be migrated (if the app is deprecated).

The OpenDoc method compares the version of the app with the version of Qlik Sense and migrates the app to the current version of Qlik Sense if necessary. Once the migration is done, the app is opened.

If no migration is needed, the app is opened immediately.

The following applies:

* The app version is lower than 0.95: no migration is done. Apps older than the version 0.95 are not supported.

* The app version is at least 0.95 and less than the Qlik Sense version: the app is migrated and then opened.

* Qlik Sense and the app have the same version: the app is opened, no migration is needed.

If the app is read-only, the app migration cannot occur. An error message is sent.
