Please consider if a backup of the config settings of the Azure sync tool including the OU filtering be stored in Azure. So that when the AD sync connects after authentication from the on-prem server , then a check is made with the existing config layout , with a prompt to either use existing config layout if exists or continue with manual entry of config layout. Then after any changes made to display the differences before confirming updating with Azure AD. This helps as a precaution to avoid loss of complete service functionality with user dependencies.
In the event the sync tool has to be rebuilt, re-installed this will reduce service impact on users as more complex features are added in the evolving sync tool and have some redundancy to avoid users suddenly loosing access etc
