Step C: Locate the Software

1. Find the version of the software that you're downgrading to.

   Important

   If you meet the conditions in Downgrade Special Consideration, locate and download version 2.1.3 as well as the version that you're downgrading to.

   Follow these steps:

   1. From a Linux prompt, log in to the hardware until with the "elemental" user credentials.

   2. Look for the desired installer as shown here:

      [elemental@hostname ~] ls

      Look for the file named similar to this ...elemental_production_delta_2.2.0.123456.run...

2. If you find the software, skip to Step D: Downgrade the Node.

   If the software isn't on the hardware unit, go to the next step.

3. From your regular workstation, open a web browser, go to AWS Elemental Support Center Activations and download the software for the version that you're going to.

4. Make a note of where downloads are stored on your workstation. For example:

   h:/corporate/downloads/.

5. Make a note of the name of the download file. For example: elemental_production_delta_2.2.0.123456.run

6. Copy the download file from your workstation to /home/elemental/ on one of the nodes. For example:

   • Use SFTP protocol and an FTP client application on your workstation computer. Connect to the IP address for AWS Elemental Delta on port 22 with the elemental user credentials and transfer the file.

   • Use SCP protocol and an SCP client application on your workstation computer. Copy the file with the elemental user credentials and transfer the file.

7. Repeat the download to any other nodes that are changing versions. If you're changing versions on several nodes, copy the download file to every hardware unit at once. Doing so reduces downtime on each node as you start installing the new software.
