Get ready for the in-place upgrade
Before we start the upgrade, export files from the source system and prepare your system for upgrade. Follow the steps below:
Update the configuration manager extension
Upgrading ThingWorx Navigate from 1.6.x and 1.7.x to 1.9
1. First, remove the extension for configuration management. In ThingWorx Composer, click Manage iconManage, and then click EXTENSIONS. The Manage Extensions page opens.
2. Select thingworx-navigate-configuration-manager, and then under Actions, click Delete to delete the extension.
3. Restart Apache Tomcat.
4. Next, import the ThingWorx Navigate extension for configuration management from ThingWorx-Navigate-Upgrade-<version>-bundle.zip of Navigate 1.9.
5. In ThingWorx Composer, click Import/Export > EXTENSIONS > Import.
6. In the Import Extensions window, click Browse and select thingworx-navigate-configuration-manager-<version>.zip.
7. Click Import.
Upgrading ThingWorx Navigate from 1.8.x to 1.9
1. When the thingworx-navigate-configuration-manager.zip already exists on the source server, there is no need to remove it.
2. When the thingworx-navigate-configuration-manager.zip is not on the source server, follow the steps below:
a. From the PTC Software Download page, select PTC Smart Connected Applications.
b. Expand Release APPS, ThingWorx Navigate 1.9, and Most Recent Datecode.
c. Download the ThingWorx-Navigate-Upgrade-<version>-bundle.zip and extract it.
d. In ThingWorx Composer, click Import/Export > EXTENSIONS > Import.
e. In the Import Extensions window, click Browse and select thingworx-navigate-configuration-manager-<version>.zip.
f. Click Import.
Back up your custom tasks
If you have custom tasks that were built by modifying out-of-the-box ThingWorx Navigate extensions, make backups, so you can redeploy them after the upgrade. This prevents overwriting of these custom tasks during the upgrade process. For more information, see ThingWorx Extension Development Guide.
Export the configurations
Export your ThingWorx Navigate configuration from the source system. You will need to import the configuration into the target system later.
To export the file to ThingWorx complete the following steps:
1. In ThingWorx Composer, click Browse iconBrowse, and then under MODELING, click Things.
2. Search for DataConfigurationAPI and click to open it.
3. Click Services. The services open.
4. For ExportDataToFile, under Execute, click to execute the service.
5. Under fileName enter the name of the JSON file where you’ll store the exported configuration.
6. Click Execute. A confirmation message appears, and the exported file is saved to this default location: \ThingworxStorage\repository\NavigateFileRepository\.
Prepare the system for upgrade
Import the file for the latest release to prepare the system for upgrade.
