Tamr Core Releases

Important Information for All Releases

Upgrading Tamr Core to a New Release

Follow the upgrade instructions in the Tamr Core documentation for the version to which you are upgrading. If the version to which you are upgrading has patch releases, Tamr strongly recommends installing the latest patch to ensure you have the latest fixes and security enhancements.

Depending on the version from which you are upgrading, you may need to install required checkpoint releases as part of your upgrade path.

Required Checkpoint Releases

When you upgrade Tamr Core, you must upgrade to each of the intervening checkpoint versions before upgrading to a later version.

The following Tamr Core releases are checkpoint releases:

  • v2022.002
  • v2022.001
  • v2021.002
  • v2020.016
  • v2020.004

The upgrade utility prevents you from upgrading past a checkpoint version. For example, the following upgrade paths are allowed: v2020.017 -> v2021.002, v2021.001 -> v2021.002. These upgrade paths are prevented: v2020.016 -> v2021.003, v2019.019 -> v2021.002.

Installing Patch Releases

For every software release version that has a patch, Tamr strongly recommends that you upgrade to the most recent patch. To install the most recent patch, follow the upgrade instructions and supply the version number of the patch as the version for your upgrade.

If you want to upgrade directly to a patched version, specify the --skipCheckpointReleaseValidation flag when installing Tamr Core. For information, see Upgrading.

Obtaining Release Binary Files

Contact Tamr Support for release binary files for installation and upgrade. Checksums are available for binary validation.
