Prepare for the Upgrade
Before you continue with the upgrade, you need to export your files from the source system. Complete the following steps to prepare your ThingWorx Navigate configuration for upgrade.
1. Import the file ThingWorx-Navigate-Framework-<version>.zip from ThingWorx Navigate 1.7.1:
a. From the PTC Software Download page, select PTC Smart Connected Applications.
b. Expand Release APPS, ThingWorx Navigate Framework Extension, and Most Recent Datecode.
c. Download ThingWorx Navigate Framework Extension for ThingWorx Navigate 1.7.1 build: ThingWorx-Navigate-Framework-<version>.zip, and extract the zip file.
d. Import XML files, depending on your current version of ThingWorx Navigate:
ThingWorx Navigate 1.5.x—Import PrepareForUpgrade_Navigate-1_5_0.xml from the ThingWorx-Navigate-Framework-<version>.zip of ThingWorx Navigate 1.7.1 build.
ThingWorx Navigate 1.6.0—No import necessary.
ThingWorx Navigate 1.6.1—Import PrepareForUpgrade_Navigate-1_6_1.xml from the ThingWorx-Navigate-Framework-<version>.zip of ThingWorx Navigate 1.7.1 build.
2. If you have custom tasks that were built by modifying out-of-the-box ThingWorx Navigate extensions, create 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 Development Guide.
