Can I still make modifications, changes, updates to my REDCap project after moving to production?

Yes! For changes to data collection instruments, longitudinal events, and some other project modifications, you must first go to the Online Designer and select Enter Draft Mode. You can then make modifications, return to the Online Designer, and Select Submit Modifications for Review. Many modifications will go through automatically. For example, adding field or instruments does not affect data already collected. However, some changes require administrator review such as deleting records, deleting instruments, changing choices to multiple choice fields, etc. in order to prevent issues to data already collected.

Modifications to survey settings, Alerts & Notifications, Automated Survey Invitations, Survey Queue, can all be made without going to Draft Mode. Be sure to test any changes to these settings by adding a test record to the project.
