Please find the complete changelog in our release notes on our WEB site.
The sip:provider CE system upgrade to mr6.1.2 will be performed in several steps:

Ensure you are using the Sipwise APT repositories. Public Debian mirrors may not provide packages for old Debian releases anymore. Also, they might be outdated. Consider using Sipwise repositories for the time of the upgrade. |
Execute the following commands as root:
echo "# Please visit /etc/apt/sources.list.d/ instead." > /etc/apt/sources.list
mkdir -p /etc/apt/sources.list.d
for file in /etc/apt/sources.list.d/*.list ; do mv "${file}" "${file}.DISABLED" ; done

Do not use "ngcpcfg apply/build" after executing the steps from the above block, as otherwise the changes will be overwritten and you will have to redo these steps. |
Run "apt-get update" and ensure you have no warnings/errors here.
Sipwise NGCP introduces Maintenance Mode with its mr5.4.1 release. The maintenance mode of NGCP will disable some background services (for instance: mediator) during the software upgrade. It thus prevents the system from getting into an inconsistent state while the upgrade is being performed. You can activate maintenance mode by applying a simple configuration change as described later.
ngcpcfg set /etc/ngcp-config/config.yml "general.maintenance=yes"
ngcpcfg apply 'Enabling maintenance mode before the upgrade to mr6.1.2'
To upgrade the sip:provider CE to release mr6.1.2, execute the following commands:
NGCP_CURRENT_VERSION=$(cat /etc/ngcp_version) sed -i "s/$NGCP_CURRENT_VERSION/mr6.1.2/" /etc/apt/sources.list.d/sipwise.list apt-get update apt-get install ngcp-upgrade-ce
Run the upgrade script as root like this:
ngcp-upgrade
| info | |
sip:provider CE can be upgraded to mr6.1.2 from previous release or previous build only. The script ngcp-upgrade will find all the possible destination releases for the upgrade and allow to choose the proper one. |
| info | |
If there is an error during the upgrade, the ngcp-upgrade script will
request you to solve it. Once you’ve fixed the problem, just execute
|
The upgrade script will ask you to confirm that you want to start. Read the given information carefully, and if you agree, proceed with y.
The upgrade process will take several minutes, depending on your network connection and server performance. After everything has been updated successfully, it will finally ask you to reboot your system. Confirm to let the system reboot (it will boot with an updated kernel).
Once up again, double-check your config file /etc/ngcp-config/config.yml (sections will be rearranged now and will contain more parameters) and your domain/subscriber/peer configuration and test the setup.
In order to disable the maintenance mode, do the following:
ngcpcfg set /etc/ngcp-config/config.yml "general.maintenance=no"
ngcpcfg apply 'Disable the maintenance mode after the upgrade to mr6.1.2'
When everything has finished successfully, check that replication is running.
Check ngcp-status.
Finally, do a basic functionality test.
Check the web interface, register two test subscribers and perform a test call
between them to ensure call routing works.

You can find a backup of some important configuration files of your existing installation under /var/backup/ngcp-mr6.1.2-* (where * is a place holder for a timestamp) in case you need to roll back something at any time. A log file of the upgrade procedure is available at /var/backup/ngcp-mr6.1.2-*/upgrade.log. |
If your current release is already the latest or you prefer to be on the LTS release, we still suggest appling the latest hotfixes and critical bug fixes.
Execute all steps as described in Section 14.2, “Upgrade from previous versions to mr6.1.2”. They include the system checks, customtt handling and others. It is important to execute all the steps from the above chapter.
