Pre-Upgrade Procedures

This section explains the procedures that must be performed before upgrading to version 23.04.

The pre-upgrade procedures are:

1. Backing up the Data Store
2. Transferring file to the Docker host that deployed Skylight orchestrator Docker
3. If operating in a Hot Standby configuration, stop the redundancy feature

Backing up the Data Store

A database backup of the system is needed.

Requirement:

Skylight orchestrator services must be started.

To back up the mysql database

1. Open an SSH terminal session to the Skylight orchestrator CLI on port 2200.
2. Log in as the skylight user.
3. Create a backup of the data store by entering:

database backup

---

Notes:

On the Non-Hot Standby configuration system, the backup is generated as a tar.gz file in the folder ‘backups’ of the ‘so-mysql’ volume.

On the Hot Standby configuration system:

• The backup must be taken from the active site.
• The backup is generated as a tar.gz file in the folder '/home/skylight/so/mysql-ha/backups'

---

Transferring File to the Docker host which deployed the Skylight orchestrator Docker

This procedure explains how to install the required upgrade script to the appropriate location.

The following upgrade file must be available:

• docker-dist-23.04-GA-10.sh

To transfer file

The procedure must be executed by the skylight user.

1. From your computer, use an SCP client (such as WinSCP) and the Skylight user to transfer the required file to the /home/skylight folder.

---

CAUTION: The location of the required file must be /home/skylight.

---

If operating in a Hot Standby configuration, stop the redundancy feature

1. Open an SSH terminal session to the Skylight orchestrator CLI on port 2200.
2. Log in as the skylight user.
3. Stop the redundancy feature process by entering:

redundancy control stop

---

Note: Redundancy feature can be stopped on both sites by running above command on a site only.

---

Post-Installation Procedures

This section explains the procedures applicable after your upgrade.

The post-installation procedures are:

1. Restarting the Skylight orchestrator services
2. Post-Upgrade Checks

Restarting the Skylight orchestrator services

This procedure will start the upgraded software.

Restarting the Skylight orchestrator services for Hot Standby configuration

1. Open an SSH terminal session to the Skylight orchestrator CLI designated as the preferred active site on port 2200.

2. Log in as the skylight user.

3. Configure the preferred site to last active site, enter:

redundancy config preferred {site-a | site-b}

4. Start the Hot Standby process by entering:

redundancy control start

5. Verify redundancy status by entering:

redundancy show status

Restarting the Skylight orchestrator services for a Non-Hot Standby configuration

1. Open an SSH terminal session to the Skylight orchestrator CLI on port 2200.

2. Log in as the skylight user.

3. Start services by entering:

services start

4. When prompted enter:

y

---

Note: It may take up to 10 minutes for the Skylight orchestrator services to be healthy.

---

Verifying the Startup Status

To verify the startup status

1. Enter:

services status

A list of services (that are currently running) is displayed.
Ensure that the state of all services is shown as healthy.

2. Close the terminal session to port 2200 by entering:

exit

Post-Upgrade Checks

The final step of the upgrade is to check the network inventory and ensure that Skylight orchestrator Docker is operational. The following steps constitute a basic verification of the state of Skylight orchestrator.

To verify network inventory and check Skylight orchestrator functionality

1. Log in to the Skylight orchestrator web application in a supported web browser.
2. Click the Accedian icon to display the About window.
   The Build Version should indicate version 23.04.
3. Access the Device ▶ Managed Elements tab and verify that the total count of network elements at the bottom-left corner is accurate.
4. Click the icon at the bottom-right corner and verify that the current alarm count is accurate.
5. Access the Commission ▶ Jobs tab and verify that any pre-existing configuration jobs are still present.
6. Access the Collection ▶ Reporting Status tab and verify the following:
   • The list of performance elements with a pm collect agent.
   • The CSV time and Transfer time have both recently been updated for all elements with streaming enabled.
7. Access Admin ▶ Licensing to verify that the current License server is the as same as before upgrading:
   • Verify that the License server is Integrated Server if you imported the "Skylight-orchestrator - Internal License server" key on the Skylight orchestrator before upgrading​.
   • Verify that the connection with SDLS has been established if you configured the Skylight orchestrator connection to the license server before upgrading.

   ---

   Note: Importing "Skylight-orchestrator - Internal License server" key after upgrading Skylight orchestrator is no longer required.

   You can promptly change the license server from ‘Integrated Server' to 'SDLS’ and vice versa without restarting app_server.

   ---

8. Check your session status by accessing Sessions tab.

---

Note: All functionality is added by default; importing Feature Activation Key in order to enable functionalities after upgrading Skylight orchestrator is no longer required.

---

Rollback Procedure

This section explains how to roll back to the original operating system partition and restore the system to its initial state.

If you must roll back a cluster deployment, you must repeat the procedure on all appliances on which the upgrade was performed (successfully or unsuccessfully).

Rollback for Skylight orchestrator Procedure

This procedure explains how to roll Skylight orchestrator back to the previous release.

You would only need to perform the rollback procedure if problems occur during the appliance upgrade procedure, such as:

• An error message occurs during the upgrade process that prevents you from proceeding.
• The upgrade process terminates unexpectedly.
• The application does not function as expected after the upgrade.

Procedure Requirements

The following requirement applies to the procedure:

1. This procedure must be executed with one user having sudo privileges or root access on the host.

If operating in a Hot Standby configuration, stop the redundancy feature

1. Open an SSH terminal session to the Skylight orchestrator CLI on port 2200.

2. Log in as the skylight user.

3. Stop the Hot Standby process by entering:

redundancy control stop

---

Note: Redundancy feature can be stopped on both sites by running above command on a site only.

---

Rolling back the upgrade

Repeat this procedure on all appliances that were upgraded.

To roll back the upgrade

1. Using an SSH terminal session to port 22 of the appliance, log in to the appliance with one user having sudo privileges or root access on the host.
2. Execute the script that does the partition upgrade:

sudo sh /home/skylight/docker-dist-23.04-GA-10.sh -r

If prompted, provide the password of the user having sudo privileges or root access on the host.
