# Downloading the Upgrade Packages for an AWS Deployment

Use this procedure to download the packages for installation or upgrade:

1. To identify the files to download to your secure network location, see "Downloading and Installing the ArcSight Platform Installation Files" in the Release Notes for ArcSight Platform 23.3.

2. From a secure network location, download the installation packages for the OMT Installer and the products of your choice, along with their signature files (.sig).

   Note: This secure network location must be able to access your instance of AWS.
   Important: Before proceeding with the next step, verify the GPG digital signatures of the downloaded files as the per this knowledge base article.

3. Extract the`arcsight-platform-cloud-installer-XX.X.X.XXX.zip` file.

4. Review the following table to understand the utility scripts and some templates used during the AWS deployment of ArcSight Platform. The utility scripts and templates are located in the `aws_scripts/scripts` directory.

   Script | Description
   --- | ---
   `generate_aws_ secrets` | Generates new Kubernetes Secrets for connecting from the cluster to the Elastic Container Registry (ECR). Important: The generated credentials and secrets are valid only 12 hours after generation. If the credentials and secrets have expired, use this script following the instructions in Refresh the ECR credentials in the K8s.
   `init_efs` | Creates the required folder structure on the Elastic File Storage (EFS) and assigns correct ownership and permissions. You will use this script when configuring EFS for the ArcSight Suite. Parameters for this script are discussed in the following sections. Note: Execute this script without parameters to display the help.
   `upload_images_to_ECR` | Uploads the OMT and product images to the ECR to make them accessible to K8s. The script performs tasks in the background required specifically by the AWS ECR. Parameters for this script are discussed in the following sections. Note: Execute this script without parameters to display the help.
   `workernodes-userdata` | The installation uses this script indirectly for enabling worker nodes to join the Kubernetes cluster.
