Is it a good practice to populate the 'To' Date of the burden structures?

Summary:

Due to changes in expenditure types (like the elimination of an expenditure type, changes in the policy with respect to costs included in the calculation of burdening F&A), we have had to revise expenditure types (example: Mod Tot Dir Cost TG-Rev 001 is updated to Mod Tot Dir Cost TG-Rev 002). Would it be recommended that the 'to date' of burden structure Mod Tot Dir Cost TG-Rev 001 be populated? The date would be the day before the burden structure Mod Tot Dir Cost TG-Rev 002 is activated (from date). What precautions should the organization take in
