In general, we migrate all past records contained in your previous MIS (such as SIMS) to Arbor. The limit is the data in your previous MIS - we can only migrate what's stored there.
This means that, for example, we would migrate student and staff records even if they have since left your school. You'll still be able to find these records using the Global Search, and remove them as needed using the Data Retention process.
Please note that:
- This only applies to data we do migrate.
- The data we migrate will ensure you are census-ready, but there may be more areas you want to check or add. Please see our guidance here: Getting your new Arbor site School Census ready
Please see our list of FAQs on whether each item migrates. It will detail whether there are time limits to the data that is migrated (such as logs of Detention sessions only migrating for the current academic year: Common Migration FAQs
