Upgrade Platform Analytics from an Earlier Version
The Platform Analytics installer includes an upgrade path from earlier versions of each installed component. When the current installer runs, it checks for any previous installations. 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 repair or modify your existing server installation. For more information about reinstalling, see Repair or Modify an Existing Installation
* 
When you upgrade an earlier version, the new version is installed in the old installation directory. The old directory will be preselected during installation.
The upgrade process migrates all the data related to existing jobs and results. Log files are preserved. When the upgrade is complete, the installer continues its deployment process. If the upgrade fails, the installer rolls 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.
When you modify or repair 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 modify or repair.
* 
As an extra precaution, if upgrading installation of the Property Transform component, back up the workdir folder of your existing installation before you run the upgrade.
Note that an upgrade to Platform Analyticscomponents will likely require an upgrade to yourThingWorxserver as well. TheThingWorxserver must be upgraded before you run thePlatform Analyticsinstaller.
Notes for Upgrading Descriptive Analytics
Beginning with the 8.4 release, Descriptive Analytics is installed as part of the Platform Analytics installer. However, in previous releases, Descriptive Analytics was installed via the Analytics Server installer. For this reason, when a version of Descriptive Analytics from 8.3 or earlier is detected during 8.4 or later installation, it must be removed manually before the newer installation can launch successfully.
* 
The manual removal in necessary only when upgrading from an 8.3 or earlier version. When upgrading from 8.4 to a subsequent release, the manual step is not necessary.
To remove pre-8.4 versions of Descriptive Analytics:
1. Open the Windows Explorer and navigate to the ThingWorxAnalytics installation directory.
2. Right click the following uninstall file and select the option to Run As Administrator:
DescriptiveAnalytics/DescriptiveAnalytics_uninstall.exe
A Question window opens asking you to confirm that you want to uninstall the selected program and all its modules.
3. Click Yes.
You might be asked to confirm a second time. Then the Uninstalling screen opens. When the process finishes, another window opens to let you know the uninstall is complete.
4. Click OK to close the window.
Descriptive Analytics is uninstalled from your system.
5. To ensure that all related files are removed, in the Windows Explorer, navigate to the ThingWorxAnalytics installation directory, and delete the entire Descriptive Analytics directory.
