Hi @vi1.
Your procedure for upgrading will vary depending on the extensions installed. If you are running ThingWorx Apps (Manufacturing and Service Apps), there are additional steps required for upgrade. There are also specific requirements around Navigate. You will need to check the specific product documentation for any apps running under ThingWorx for planning your upgrade.
If you are running extensions from the Marketplace, some of those extensions may no longer be compatible or require upgrade. Note that a number of extensions have been removed from the Marketplace for review and are currently not available for download. Some extensions may require no update. If you have any custom extensions, it may be necessary to make modifications to ensure compatibility with 8.5.
When planning an upgrade, it's recommended that you take sufficient backups to ensure the ability to revert if issues are encountered. These backups should include:
- Database dump
- Backup of the complete folder structure for \ThingworxStorage
- Backup of the complete folder structure for \ThingworxPlatform
- Backup of the complete folder structure for <tomcat_home>
It's always recommended that you test your upgrade procedure in a non-prod environment and then perform full regression testing to identify any issues. It will be necessary to run the upgrade scripts identified for your database platform when upgrading major/minor releases, as in your case.
Please refer to this document to help you prepare for your upgrade. In addition, please validate that all system requirements are being met by reviewing this document.
Regards.
