+# On-Premise Business
+
+**On-Premise Business** is our paid plan that provides access to advanced features and extensions for self-hosted solidtime instances.
+
+To learn more about the On-Premise Business plan and see detailed pricing information, please visit our [pricing page](https://www.solidtime.io/pricing).
+
+## Getting Started
+
+Once you subscribe to the On-Premise Business plan, you'll receive an email with the following license information:
+
+1. Docker registry
+2. Username
+3. Password
+
+## Upgrading an existing Instance
+
+If you already have a solidtime instance running, you can upgrade it to On-Premise Business.
+
+:::warning
+
+We highly recommend making a backup of your data before proceeding.
+
+:::
+
+
+### 1. Login to the private registry
+
+First, you need log into the private registry by running the following command on the host machine:
+
+```bash
+docker login registry.on-premise.solidtime.io
+```
+
+You will be asked to provide a **Username** and **Password**, which are included in the license information mail.
+
+### 2. Upgrade Docker images
+
+Now, we have to change the images from the [public registry](https://hub.docker.com/r/solidtime/solidtime) to the private one in the `docker-compose.yml` for the services **app, scheduler and queue**.
+
+`solidtime/solidtime` -> `registry.on-premise.solidtime.io/solidtime/solidtime`
+
+After doing that the image attributes in your `docker-compose.yml` for **app, scheduler and queue** should look something like this:
+
+```yaml
+services:
+  app:
+    // highlight-next-line
+    image: "registry.on-premise.solidtime.io/solidtime/solidtime:${SOLIDTIME_IMAGE_TAG:-latest}"
+    # more config...
+
+  scheduler:
+    // highlight-next-line
+    image: "registry.on-premise.solidtime.io/solidtime/solidtime:${SOLIDTIME_IMAGE_TAG:-latest}"
+    # more config...
+
+  queue:
+    // highlight-next-line
+    image: "registry.on-premise.solidtime.io/solidtime/solidtime:${SOLIDTIME_IMAGE_TAG:-latest}"
+    # more config...
+```
+
+### 3. Restart the services
+
+After changing the config we need to pull the new images and restart the services.
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+### 4. Run database migrations
+
+The On-Premise Business Features have additional database tables, so in order to apply the migrations, run the following command:
+
+```bash
+docker compose exec scheduler php artisan migrate --force
+```
+
+### 5. All done!
+
+solidtime should now run with all additional features of the On-Premise Business plan. If you run into any issues, please contact us at [hello@solidtime.io](mailto:hello@solidtime.io).
