Hi Nagesh, 1. Your 2.4.x won't be supported here. 2. See slapcat and slapadd to dump and reload your DB from BDB to MDB 3. See "mdb_stat/dump/copy/load" Chris Paul | Rex Consulting | https://www.rexconsulting.net Hi Team, We are migrating openldap from 2.4.51 to 2.6.2 and we have the following queries 1. What is the End of life date for 2.4.x series? 2. OpenLdap 2.6.x doesn't have BDB Data base Support but has MDB, but in our existing machines where 2.4.51 is installed. Our data is populated in ".BDB" files. So is there is any guide where and how our data will be migrated from .BDB format to .MDB format ? 3. There is a utility db_verify which verifies .BDB files which is not working for .MDB files. What is utility to verify .MDB data files? Best Regards, Nagesh
