:::note 
For upgrade purposes, the terms **Trains Server** and **ClearML Server** are interchangeable.  
:::
 
The sections below contain the steps to upgrade **ClearML Server** on the [same AWS instance](#upgrading-on-the-same-aws-instance), and 
to upgrade and migrate to a [new AWS instance](#upgrading-and-migrating-to-a-new-aws-instance).

### Upgrading on the Same AWS Instance

This section contains the steps to upgrade **ClearML Server** on the same AWS instance.

:::warning
Some legacy **Trains Server** AMIs provided an auto-upgrade on restart capability. This functionality is now deprecated.
:::

**To upgrade your ClearML Server AWS AMI:**

1. Shutdown the **ClearML Server** executing the following command (which assumes the configuration file is in the environment path). 
    
        docker-compose -f /opt/clearml/docker-compose.yml down

   If you are upgrading from **Trains Server**, use this command:

        docker-compose -f /opt/trains/docker-compose.yml down

1. We recommend [backing up your data](clearml_server_aws_ec2_ami.md#backing-up-and-restoring-data-and-configuration) and, 
   if your configuration folder is not empty, backing up your configuration.

1. If upgrading from ClearML Server version older than 1.2, you need to migrate your data before upgrading your server. See instructions [here](clearml_server_mongo44_migration.md). 
If upgrading from Trains Server version 0.15 or older, a data migration is required before continuing this upgrade. See instructions [here](clearml_server_es7_migration.md).
   
1. If upgrading from **Trains Server** to **ClearML Server**, rename `/opt/trains` to `/opt/clearml`.

1. Download the latest `docker-compose.yml` file. Execute the following command:

        sudo curl https://raw.githubusercontent.com/allegroai/clearml-server/master/docker/docker-compose.yml -o /opt/clearml/docker-compose.yml
        
1. Startup **ClearML Server**. This automatically pulls the latest **ClearML Server** build.

        docker-compose -f /opt/clearml/docker-compose.yml pull
        docker-compose -f docker-compose.yml up -d

### Upgrading and Migrating to a New AWS Instance

This section contains the steps to upgrade **ClearML Server** on the new AWS instance.

**To migrate and to upgrade your ClearML Server AWS AMI:**

1. Shutdown **ClearML Server**. Executing the following command (which assumes the configuration file is in the environment path).

        docker-compose down

1. On the old AWS instance, [backup your data](clearml_server_aws_ec2_ami.md#backing-up-and-restoring-data-and-configuration) 
   and, if your configuration folder is not empty, backup your configuration.

1. If upgrading from **Trains Server** version 0.15 or older, a data migration is required before upgrading. First follow 
   these [data migration instructions](clearml_server_es7_migration.md), and then continue this upgrade.

1. On the new AWS instance, [restore your data](clearml_server_aws_ec2_ami.md#backing-up-and-restoring-data-and-configuration) and, if the configuration folder is not empty, restore the 
   configuration.

1. Startup **ClearML Server**. This automatically pulls the latest **ClearML Server** build.

        docker-compose -f docker-compose.yml pull
        docker-compose -f docker-compose.yml up -d
