Display the system information and status.
Log in to the old deployer VM using SSH.
-
Back up the necessary files from the deployer VM.
Copy the following files to a directory that is outside of the deployer VM:
-
SSH files
/root/.ssh/id_rsa
/root/.ssh/id_rsa.pub
/root/.ssh/known_hosts
-
the input JSON configuration and user values YAML file (if any) that were used to install the Fabric Services System, for example:
/root/customer-input.json
/root/user_values.yaml

/root/tls.crt
/root/tls.key

Temporarily remove all ACL and QoS profiles configured in the system.
See the Release Notes for background information about this step. For instructions, see the
ACL profile management
andQoS profile management
sections in the Fabric Services System User Guide. -
Shut down the old deployer VM.
Note: Ensure that the old deployer VM is not configured to automatically restart.
-
Create a new deployer VM using the image for the new release.
For instructions, see Fabric Services System deployer VM creation. The new deployer should have the same network configuration and the same IP address of old deployer VM.
- Copy the files that you saved in Step 2 to the new deployer VM in the same locations.
