Do the slapcat on ldap2 and then delete the db files on ldap1 and then run the slapadd. you will not get duplicates because all of the CSN's will be the same. This is what I have done my migrations to the most recent versions and doing my own builds. Works great that way.
Huh? The CSNs contain the server IDs. Servers ignore their own changes. --Quanah -- Quanah Gibson-Mount Architect - Server Zimbra, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration
