Upgrade Analytics Server from an Earlier Release
The
Analytics Server installation includes an upgrade path from earlier versions that are still under standard support. When the current installer runs, it checks for these previous installations of the server. If an earlier release is detected, you are prompted to upgrade. If the installer detects the current release already installed, you are prompted to reinstall. Reinstallation can be useful to modify or repair your existing server installation. For more information about reinstalling, see
Repair or Modify an Existing Installation.

If you are upgrading from a release earlier than 8.4, you will need to upgrade to 8.4 first. Then you can upgrade to the current version.
|
The upgrade process migrates all the data related to existing jobs and results. Log files are preserved. When the upgrade is complete, the installer will continue its deployment process. If the upgrade fails, the installer will roll back all changes. When an upgrade completes successfully, it cannot be rolled back to the previous version. So, be sure that you want to keep the upgrade before you opt to run it.

As an extra precaution, back up the data folder of your existing installation before you run the upgrade.

Notes for Upgrading ThingWorx Analytics Server
• When you upgrade an installation, only configuration parameters you were prompted for during the original installation are persisted. Any custom configuration changes made to properties or service files are reset to their default values and must be manually reconfigured after the upgrade.
• When you upgrade an earlier version of ThingWorx Analytics Server, the new version is installed in the old installation directory. The old directory will be preselected during installation and you will not be able to change it.
• An upgrade to the ThingWorx Analytics Server will likely require an upgrade to your ThingWorxserver as well. The ThingWorx server must be upgraded before you run the Analytics Server installer.
