What will be/can be the best possible way to track a student’s journey if they switch tenants?

Every learner within the system has a Universal Learner Id that follows the learner life-long across the different stages of learning from K12, Higher Ed, Professional learning irrespective of the tenant they may be in each stage. So, when a learner moves from one organization to another within Gooru Navigator, the learner identity including proficiency in various facets, their portfolio, preferences and all the different attributes of the learner is available and accessible in the new organization.
