Upgrade a Single Node Cluster Environment with the Delta Bundle

Note

  • While system upgrade takes approximately two hours at a single site, this may vary in accordance with your topology, number of devices and subscribers. Adjust your upgrade maintenance window to allow for your configuration.

The standard screen command should be used where indicated. See: Using the screen command.

Schedules, Transactions and Version Check

Description and Steps

Notes and Status

Turn off any scheduled imports to prevent syncs triggering part way through the upgrade. Two options are available:

Individually for each job:

  1. Log in on the GUI as a high level administrator above Provider level.

  2. Select the Scheduling menu to view scheduled jobs.

  3. Click each scheduled job. On the Base tab, uncheck the Activate check box.

Mass modify:

  1. On the GUI, export scheduled syncs into a bulk load sheet.

  2. Modify the schedule settings to de-activate scheduled syncs.

  3. Import the sheet.

Schedules enabled on the CLI:

  1. Run schedule list to check if any schedules exist and overlap with the maintenance window.

  2. For overlapping schedules, disable. Run schedule disable <job-name>.

Check for running imports. Either wait for them to complete or cancel them:

  1. Log in on the GUI as a high level administrator above Provider level.

  2. Select the Transaction menu to view transactions.

  3. Filter the Action column:

    1. Choose Status as “Processing” and then choose each Action that starts with “Import”, for example, “Import Unity Connection”.

    2. Click Search and confirm there are no results.

    3. If there are transactions to cancel, select them and click Cancel.

Customized ``data/Settings``

If data/Settings instances have been modified, record these or export them as JSON.

The modifications can be re-applied or exported JSON instances can be merged following the upgrade. See: Post Template Upgrade Tasks single node cluster (Maintenance Window).

Version

Record the current version information. This is required for upgrade troubleshooting.

  • Log in on the GUI and record the information contained in the About > Extended Version

Pre-Upgrade, Security and Health Steps

Description and Steps

Notes and Status

Validate the system health.

diag health

If there is any sign of the paths below are over 80% full, a clean-up is needed to avoid risk of full logs occurring during upgrade. Clean-up steps are indicated next to the paths:

/              (call support if over 80%)
/var/log       (run: log purge)
/opt/platform  (remove any unnecessary files from /media directory)
/tmp           (reboot)

Verify there are no pending Security Updates:

security check

Create a restore point.

As part of the rollback procedure, ensure that a suitable restore point is obtained prior to the start of the activity, as per the guidelines for the infrastructure on which the VOSS Automate platform is deployed.

VOSS cannot guarantee that a restore point can be used to successfully restore VOSS Automate. If you cannot restore the application from a restore point, your only recourse is to reinstall the application.

After the restore point has been created, restart.

Optional: If a backup is required in addition to the restore point, use the backup add <location-name> and backup create <location-name> commands. For details, refer to the Platform Guide.

Description and Steps

Notes and Status

Before upgrading, check all services:

Make sure no services are stopped/broken. The message ‘suspended waiting for mongo’ is normal on a fresh node.

  • app status

Verify the node is not in the ‘recovering’ state (stateStr is not RECOVERING)

  • database config

Upgrade

Description and Steps

Notes and Status

It is recommended that the upgrade steps are run in a terminal opened with the screen command.

  • screen

Run (optionally with command parameters below):

  • app install media/<script_file>

From release 19.1.2 and later, the delete-on-success parameter and yes or no value have been added to remove or keep the the script file in the media/ directory after successful installation.

Note that during the upgrade, phone registration data is cleared. A message will show in the log: Remove phone registration data. This is required so that old values are not displayed, since after the upgrade this information is no longer stored in the resource cache.

Note

In order to carry out fewer upgrade steps, the updates of instances of the some models are skipped in the cases where:

  • data/CallManager instance does not exist as instance in data/NetworkDeviceList

  • data/CallManager instance exists, but data/NetworkDeviceList is empty

  • Call Manager AXL Generic Driver and Call Manager Control Center Services match the data/CallManager IP

Post-Upgrade, Security and Health Steps

Description and Steps

Notes and Status

Verify the status:

  • diag health

If upgrade is successful, the screen session can be closed by typing exit in the screen terminal. If errors occurred, keep the screen terminal open for troubleshooting purposes and contact VOSS support.

Check for needed security updates.

  • security check

If one or more updates are required, complete all the security updates.

  • security update

Note: if the system reboots, do not carry out the next manual reboot step.

Manual reboot only if needed:

  • system reboot

Post Template Upgrade Tasks

Description and Steps

Notes and Status

SSO Login URL check if needed

Verify the SSO Login URL if needed. Go to Single Sign On > SSO Identity Provider and ensure your URL matches the SSO Login URL value.

Customized ``data/Settings``

Merge the previously backed up customized data/Settings with the latest settings on the system by manually adding the differences or exporting the latest settings to JSON, merging the customized changes and importing the JSON.

Support for VG400 and VG450 Analogue Gateways

Before adding the VG400 or VG450 Gateway, the device/cucm/GatewayType model needs to be imported for each Unified CM.

  1. Create a Model Type List which includes the device/cucm/GatewayType model.

  2. Add the Model Type List to all the required Unified CM Data Syncs.

  3. Execute the Data Sync for all the required Unified CMs.

Verify the upgrade

Log in on the GUI and check the information contained in the About > Version menu. Confirm that versions have upgraded.

  • Release should show 21.3

  • Platform Version should show 21.3

If your web browser cannot open the user interface, clear your browser cache before trying to open the interface again.

  • Check themes on all roles are set correctly
