I am looking for information on what your course site retention policy is. We have recently moved to SaaS and we are contemplating leaving up course sites longer than we used to. On our Self-Hosted system we would leave the previous term taught, up for the next term and then remove the old term before releasing the next term in sequence. For example Fall 2016, Spring 2017, Summer 2017, Fall 2017 and remove Summer 2016. Then the next sequence would be Spring 2017, Summer 2017, Fall 2017, Spring 2018 and remove Fall 2016. I have found many schools that only keep 2-3 years of old terms, but none that keep everything. We do however institutionally archive every course taught and can restore any old course as requested. Thanks!
