Reconciling AD accounts

Is there a way to manually kick off an account reconciliation process? Or is a manual process needed for this instance? Long short of it: User left in 2015, accounts were disabled. They were supposed to be renamed and archived. User returns in 2018. Apparently user's administrative account was not previously renamed. It got renamed, and new account created with same (original) username in a roughly 5 minute span. Dell Data Security server currently reports both accounts with original username, in 2 different AD locations. Both also having identical UPNs. My guess is that since there was no reconciliation that occurred after original account was renamed and before new account was created, is causing issues. Any way to remediate this short of digging directly in to the database?
