Upgrading from VOSS-4-UC 18.1.3 to 19.3.2

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.

    You can follow the progress on the GUI transaction list.

  • The screen command can be used - see: Notes on the screen command

The upgrade process is in two stages:

  1. 18.3.1 to 19.2.1 ISO Upgrade
  2. 19.2.1 to 19.3.2 Delta Bundle Upgrade

Important

The process in this document only applies for the full upgrade from 18.3.1 to 19.3.2, and cannot be used for the upgrade to intermediate versions. Refer to the upgrade documents accompanying individual releases for intermediate version upgrades.

Note:

  • For each stage, the required upgrade files need to be downloaded.
  • A database filesystem conversion is required during the second, delta bundle upgrade.

Upgrade a Multinode Environment with the Delta Bundle

Notes on the screen command

From VOSS-4-UC 18.1 or CUCDM 11.5.3 onwards, the standard screen command should be used where indicated, and the reconnect parameter is available if needed:

  • screen - start a new session
  • screen -ls - show sessions already available
  • screen -r [screen PID] - reconnect to a disconnected session

We recommend using the screen command to avoid failures if the connection is interrupted whilst running the command. If the connection is interrupted whilst running the command in screen then the session can be retrieved by first listing the sessions PID currently running in screen: screen -ls, and then reconnecting to the session using screen -r [screen PID].

The version of screen used in VOSS-4-UC also supports the creation of a log file. If long-running commands will be run, the log file captures screen console output up to the session timeout. A message shows:

timed out waiting for input: auto-logout

To create a screen log file:

  1. Run screen and wait for screen to open.
  2. Press <Ctrl>-a then : (colon). This will enter screen command mode at the bottom of the console.
  3. Create your screen logfile in the media/ directory:
    1. In screen command mode, type logfile media/<screen-logfilename>.log
    2. Press <Enter>
    3. Press <Ctrl>-a and then H to start writing to the log file
    4. Run your commands.

If the screen session times out, you can obtain console output from the log file, for example:

$ sftp platform@<host>:media/<screen-logfilename>.log
