Hi Scott,
It may not be necessary to delete accounts. With the LDAP setup you pick which OU's / contexts ... also there is a drop-down on the users accounts for manual or LDAP ... also there is a control in the LDAP setup on what to do if there is already a manual account (keep manual or switch to LDAP).
So, fundamentally the user "account" stays the same in Moodle you are just switching the authentication method from manual to LDAP.
On a side note, are you Scott Christy from IMHS class of 1985? Let me know...I can send you my email and we can work on this if you'd like.
Our Moodle uses both manual accounts (legacy) and LDAP for new accounts staff/students tied into our AD environment. At the start of every school year we run a report of manual accounts that have not logged in for the past 18 months or so ... we delete those ... so over time everyone will eventually use LDAP for authentication.
Thanks,
Jay
