See below for instructions on upgrading an Entrust Deployment Manager 2.0.2 installation to PKI Hub 1.1.0.

To upgrade an Entrust Deployment Manager 2.0.2 node to PKI Hub 1.1.0

1. Back up the installation state as explained in the Entrust Deployment Manager 2.0.2 guide.
2. Make sure your installation meets the Upgrade requirements
3. In all the installation nodes:
   1. Using an SFTP client, upload the pki-hub-upgrade.rpm package to the /home/sysadmin directory.
   2. Run the following command to install the package. 
      sudo dnf install pki-hub-upgrade.rpm --assumeyes
4. Run the pki-hub-upgrade prepare command sequentially on all nodes. 
   • Follow the steps described in Applying missing machine requirements if the command prompt reports missing Machine requirements – for example.
     $ sudo pki-hub-upgrade prepare

     The following tasks have to be performed to complete the preparation of the node:

     - The sda disk size needs to be increased at least to 1 TiB.

     - Follow the Entrust PKI Hub documentation on how to increase the disk size for your platform.

     - WARNING: this task may imply service outage in the node, depending on your platform.

     Once all the manual preparation tasks have been completed, re-execute the 'pki-hub-upgrade prepare' command.
   • Follow the steps described in Reinstalling Entrust Deployment Manager 2.0.2 if the command prompt requests a reinstallation – for example:
     $ sudo pki-hub-upgrade prepare

     The following tasks have to be performed to complete the preparation of the node:

     - The node needs to be reinstalled.

     - Follow the Entrust PKI Hub documentation on how to reinstall an EDM 2.0.0-based node for upgrading to Entrust PKI Hub.

     - WARNING: this task may imply service outage in the node, depending on your platform.

     Once all the manual preparation tasks have been completed, re-execute the 'pki-hub-upgrade prepare' command.
   • No additional actions are required if the prompt confirms that the node is ready for an upgrade –  for example:
     $ sudo pki-hub-upgrade prepare

     The node is ready to be upgraded to PKI Hub 1.1.0
5. Repeat the following steps sequentially on each PKI Hub node, ensuring they are not performed on multiple nodes simultaneously.
   1. Using an SFTP client, upload the CSP license file and the ISO image to the /home/sysadmin folder. 
   2. Run the pki-hub-upgrade upgrade command and wait for it to complete (around two hours) before proceeding to the next node.
      $ sudo pki-hub-upgrade upgrade --iso-path pki-hub-1.1.0.iso --license-path license.lic

      Upgrading done ╢▌▌▌▌▌▌▌▌╟ 100 %

      Successfully upgraded to 1.1.0.

      A system restart is needed.

      Previous version backups will not be able to be restored in this new version. It is highly recommended to create new backups.
       
6. Reboot all nodes sequentially.  Wait for 15 minutes before rebooting the next node.
7. Back up the installation state as explained in Backing up the PKI Hub state.
