Again, if you did not delete ANY deposits, then you should be OK.
But if you deleted even one deposit, this one will be replayed eventually. In that case, it’s better to complete the migration now, before any users perform transactions and the data becomes out of sync.
This is an issue that is common always with data migration projects. You want the snapshot you take to be of one instant in time. With careful planning you can avoid any downtime. Only enable the new site to your users once you are certain that the data is migrated correctly. You will not be able to easily perform the procedure afterwards because the user data will have diverged.
