Upgrade

Automatic upgrade

The automatic update option allows updating the software programs according to the schedule. The task start time in the cron scheduler is randomly generated. 

Log in to the control panel as root and navigate to Settings → System settings.

• Update software automatically:
  • Do not update — disable automatic updates for this control panel;
  • Update ISPsystem products — update automatically ISPsystem software products. The system updates only the packages installed from the ISPsystem repository. The packages from third-party repositories won't be updated;
  • Update all the system packages — update automatically all packages of the operating system.

Manual upgrade

Execute the following command in the console: 

/usr/local/mgr5/sbin/pkgupgrade.sh coremanager

Updating from ISPmanager 5

To upgrade ISPmanager 5 to ISPmanager 6:

1. Purchase a license for ISPmanager 6.
2. Update the control panel manually or in the Help → About program section. If your control panel version is lower than 5.295, you need to upgrade twice: first to the latest version of ISPmanager 5, and then to ISPmanager 6.

If you are using the ISPmanager 6 license and the control panel is blocked, you can update ISPmanager via the console. To do this:

1. Connect to the server with ISPmanager via SSH.

2. Download the script for updating:

   wget http://download.ispsystem.com/upgrade.ispmgr5.sh

3. Run the script:

   sh upgrade.ispmgr5.sh

Repositories

Every version has a separate repository which name matches the version name. Also, there are beta6 and stable6 repositories with all the versions of a software product. The repository defines a version the control panel can be updated to. "stable6" includes the stable and time-proved version of a software product. "beta6" includes the version that is still being tested. You can select a repository during the installation process.Switch from "stable6" to "beta6":

echo 'beta' > /usr/local/mgr5/etc/repo.version
/usr/local/mgr5/sbin/licctl fetch ispmgr
