Follow the next steps in order to enable assigning users to Stakeholders by condition:
1. Open the appsettings.xml file (located in C:\ProgramData\Bizagi\Enterprise\BizagiMC) using the text editor of your choice.
2. Within the <AppSettings> section, add the following key:
<add key="MigrateUsersToStakeholder" value="true" />
3. Restart both the Scheduler and Web Server services and try again. This should change the behavior.
4. Open Bizagi Management Console and click the Migrate button.
Once you click on it, all users that match the conditions established in Bizagi Studio will be assigned to their corresponding Stakeholder in batch.
