  * When upgrading from an existing Modular Cluster Topology that 
    was available since VOSS Automate 21.1, use the steps listed here.
  * Before upgrading to release 24.1, ensure that an additional disk is available
    for the Insights database.

    .. raw:: html 

       See: <a href="../platform/tasks-backup-restore-new-add-more-space-large-restore.html">Adding Hard Disk Space</a>
       and <a href="automate-system-hardware-specification.html">VOSS Automate Hardware Specifications</a>.

    .. raw:: latex

       See the Adding Hard Disk Space topic in the Platform Guide and VOSS Automate Hardware Specifications in the Architecture and Hardware Specification Guide.

    This disk is needed to assign to the ``insights-voss-sync:database`` mount point.
    See: :ref:`modular-Post-maintenance-mount-insights-disk`.
 
  * Before upgrading to release 24.1, ensure that sufficient time is allocated to the maintenance
    window. This may vary in accordance with your topology, number of devices and subscribers.

    The information below serves as a guideline VOSS support can be contacted if further
    guidance is required:

    * Cluster upgrade: 4h
    * Template install: 2.5h
    * For a 500K Data User system (13Mil RESOURCE documents), the expected ``upgrade_db`` step is about 12h.
    * For a 160K Data User system (2.5Mil RESOURCE documents), the expected ``upgrade_db`` step is about 2.5h.

    You can follow the progress on the Admin Portal transaction list.

  * Tasks that are marked **Prior to Maintenance Window** can be completed a few days prior to
    the scheduled maintenance window so that VOSS support can be contacted if needed and
    in order to allow for reduce down time.

   
The standard **screen** command should be used where indicated.
See: :ref:`screen-command`.

.. rubric:: Primary database and application node in a Modular Cluster Topology

* Verify the *primary application node* (UN2) with the **cluster primary role application**
  command run on the node. The output should be `true`, for example:

   ::

      platform@UN2:~$ cluster primary role application
      is_primary: true


* Verify the *primary database node* (UN1) with the **cluster primary role database**
  command run on the node. The output should be `true`, for example:

   ::

      platform@UN1:~$ cluster primary role database
      is_primary: true

Upgrade (Maintenance Window)  
............................


.. note::


   * By default, the cluster upgrade is carried out in parallel on all nodes and without any
     backup in order to provide a fast upgrade.
   * For systems *upgrading to 24.1 from 21.4.0 - 21.4-PB5*:

     * The VOSS platform maintenance mode will be started automatically
       when the **cluster upgrade** command is run. This prevents any new occurrences of scheduled transactions, including the
       24.1 database syncs associated with **insights sync**. For details on **insights sync**, see the *Insights Analytics* topic
       in the Platform Guide.
     * The **cluster maintenance-mode stop** command must however be run manually
       after the maintenance window of the upgrade: :ref:`modular-maintenance-window-manual-stop`.

   For details on the VOSS platform maintenance mode, see the *Maintenance Mode* topic in the Platform Guide.

  .. note::

     In order to carry out fewer upgrade steps, the updates of instances
     of 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

The template upgrade automatically detects the deployment mode: "Enterprise" or "Provider".      
A message displays according to the selected deployment type.

the installation propagates changes throughout the cluster.

Data migrations that are not critical to system operation can have significant
execution time at scale. These need to be performed after the primary upgrade,
allowing the migration to proceed whilst the system is in use - thereby limiting
upgrade windows.

A transaction is queued on VOSS Automate and its progress is displayed as it executes.
