Is it possbile to use MMR to my advantage to switch over? For example,
take down 1 of the servers, switch the db config from bdb to mdb, and
then restart with a blank database (with appropriate structure) and
have the MMR take care of backfilling the mdb entries? Then I wouldn't
have to export to ldif, convert the db, and reimport while possibly
loosing data from the other systems.

Hi Kyle,

I'm not sure what you are trying to avoid here... Slapcat/slapadd are always faster than sync replication. Why would you lose data from the other server while doing this? contextCSNs should be preserved w/ slapcat/slapadd, so the server being converted will just catch up using sync replication as before. You may wish to look at ITS#7427 though. The fix for that is in current RE24.
