Upgrade LiveData Migrator

We recommend you regularly upgrade LiveData Migrator so you can take advantage of new functionality and other improvements. To upgrade, run a newer version of the LiveData Migrator installer. The installer will upgrade your LiveData Migrator instance to the new version.

If you're running version 1.15.1 or lower, you need to upgrade to LiveData Migrator 1.16.0 before upgrading to any higher versions.

System users for upgrades

If you want to run the installer using a default user, run the following command:

./livedata-1.17.0-58-full_rpm_installer.sh

The default system user for the LiveData Migrator and LiveData UI services is hdfs, and the default system user for the Hive Migrator service is hive.

If you want to upgrade the product using a custom user and custom group, run the following command:

./livedata-1.17.0-58-full_rpm_installer.sh -- --user <custom user> --group <custom group>

This sets the customer user and group for all services and their respective directories.

For more information, go to Configure system users.

Before you upgrade

Configuration files stay the same after upgrading, but configuration files from the new version are also added into the same folder on an RPM installation. These new configuration files have the extension .rpmsave, and are ignored by LiveData Migrator by default. You may compare them and copy changes across accordingly, or use the new files.

The upgrade automatically overwrites shell scripts (such as start.sh) with the newer versions.

important

Do not change the value of the encrypted database password value for the UI in application-prod.properties. If the key changes, the LiveData UI will fail to start. When prompted on an Ubuntu system to keep the old application-prod.properties file or use the new one from the installer, choose to keep the existing file to prevent this.

Obtain a new installer and upgrade LiveData Migrator

Follow the installation instructions to obtain and run a new LiveData Migrator installer. This will upgrade your installed version to the latest.

LiveData Migrator conserves filesystems and migrations during an upgrade. Additionally, migrations in progress prior to the upgrade will continue as normal.

note

You may check the component versions of your current installation by running livedata-migrator --version on your LiveData Migrator host machine.
