Under the best scenario, you might start using Workforce Record Manager (WRM) right away to copy locked payroll data to the archive database. And each time payroll is processed another pay period would be copied to the archive. No data is removed from the production database until much later on. The goal is to keep Kronos Workforce Central product data your users are likely to need to access within the production database. User access to the archive database should be limited and infrequent.
