Hi Team,

We are migrating openldap from 2.4.51 to 2.6.2 and we have the following queries

• What is the End of life date for 2.4.x series?

It has already reached EOL from the project perspective.

• 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 ?

back-bdb was deprecated many years ago, and back-mdb has been the supported backend in OpenLDAP 2.4 for years. I would advise migrating your current deployment to back-mdb under OpenLDAP 2.4 prior to working on the OpenLDAP 2.6 upgrade. The general process would be:

1. export the current database(s) to ldif using slapcat 2. update the configuration to use back-mdb instead of back-bdb/hdb 3. import the LDIF file using slapadd

• 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?

back-mdb doesn't require such a utility.

1. What is the End of life date for 2.4.x series?

September 2021. https://lists.openldap.org/hyperkitty/list/openldap-announce@openldap.org/th...

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 *?

Same as for any other upgrade. slapcat / slapadd. Read the Admin Guide.

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?*

There is no such utility. LMDB is corruption proof.
