Before you upgrade PowerFlex Manager, you must back up the SSL and trusted certificates.

1. Back up the appliance SSL certificates:
   1. Log in to the PowerFlex Manager appliance using SSH and sudo to root: sudo su -
   2. Copy the following files to /home/delladmin/ or to /tmp/:
      • cp /etc/pki/tls/certs/localhost.crt /home/delladmin/
      • cp /etc/pki/tls/private/localhost.key /home/delladmin
   3. Type chown delladmin:delladmin /home/delladmin/localhost.* to change the owner to delladmin.
   4. Copy the localhost.crt and localhost.key file from the PowerFlex Manager appliance to the jump server or another Linux system for temporary storage.
