Thingworx upgrade

I am using ThingWorx Platform Release 8.5 and DatecodeSP2 Our customer is currently using ThingWorx 8.5.2-b90, which is an older platform version. We plan to propose a migration to a currently supported or latest ThingWorx version to improve platform supportability, security, performance, and future compatibility. The current environment consists of: - Current Version: ThingWorx 8.5.2-b90 - Number of Projects: 41 projects - Custom CSS: Custom CSS is implemented across all 41 projects - Existing Customizations: Custom services, widgets, UI configurations, and other project-specific customizations may be present - Migration Objective: Migrate the existing applications and configurations to the target supported/latest ThingWorx version while minimizing impact to business operations.
