Change Course Vendors - Maintain User History?

Summary

If we remove and replace old courses, can we maintain learners' records?

Content

We are considering switching our library to a new content vendor. This would mean removing old AICC courses and replacing them with new SCORM courses. 

If we do this, can we maintain our learners' learning history?  If not, how do you recommend keeping records on previous course completions?

 

Thank you!!
