| Identity Support | Identity is not supported, multi-Tenancy and Role-Based Access Control (RBAC) does not work. |
| Optimize Support | Not supported (requires Identity). |
| Connectors Deployment | Connectors can be deployed in a dual-region setup, but attention to [idempotency](../../../components/connectors/use-connectors/inbound.md#creating-the-connector-event) is required to avoid event duplication. In a dual-region setup, you'll have two connector deployments and using message idempotency is of importance to not duplicate events. |
| Connectors | If you are running Connectors and have a process with an inbound connector deployed in a dual-region setup, please consider the following: <ul><li> when you want to delete the process deployment, please delete it via Operate (not zbctl), otherwise the inbound connector won't deregister.</li><li>if you have multiple Operate instances running, then perform the delete operation in both instances. This is a known limitation which we will fix via [this ticket](https://github.com/camunda/camunda/issues/17762).</li></ul> |
