 IoT Central implements more versioning rules for device models. If you version a device template and its model in IoT Central, you can migrate devices from previous versions to later versions. However, migrated devices can't use new capabilities without a firmware upgrade. To learn more, see [Edit a  device template](../iot-central/core/howto-edit-device-template.md).

+If you want to set up your own model repository, you can use the [Azure IoT plug and play models tools](https://github.com/Azure/iot-plugandplay-models-tools) repository. This repository includes the code for the `dmr-client` CLI tool that  can validate, import, and expand DTDL models. This tool also lets you index model repositories that follow the device model repository conventions.
