Upgrading to 19.4.0ΒΆ

Pre-v19.4.0 Plixer Scrutinizer deployments must first be upgraded to v19.4.0 before being upgraded to v19.5.3 (or v19.5.4 for AWS AMI appliances), which includes the migration to Oracle Linux 9.

Follow these instructions to download the v19.4.0 installer (replace UPGRADE_VER with 19.4.0 in the download URLs) and apply the update. Once done, proceed with upgrading to the latest v19.5.x release.

Note

  • When upgrading an appliance that was previously upgraded from v18.20, the installer script will ask whether to delete the data.old backup created during that upgrade. Since a more recent backup should be created before the current upgrade process, this file can safely be deleted.

  • If a distributed cluster is being upgraded from v18.20, the prompt to create a new Plixer control key should be left blank unless encrypted keys are required. Additionally, passwords should be selected in the next step, when prompted for the login method to use for remote collectors.
