Migration and Alternatives
We provide automatic migrations or modern alternatives for all affected areas:
Roles: Existing roles are migrated automatically—your permission structure remains intact.
The migration can be initiated by users who are also authorized to create or edit roles. The migration prompt appears when a user clicks on an old role. We have provided
more information here:Rulesets: Old rulesets are adapted so that they can use the new Monthly Calendar 4.0.
The migration prompt appears when using the old Monthly Calendar—but only for users who are authorized to edit the old rule sets. The migration can be initiated directly from the prompt.
Device Module: The new “Devices” module offers expanded capabilities for integrating device telemetry and location monitoring.
Interfaces: Our APIs have been modernized—moving forward, we will rely on the GraphQL API.
