LDAP Migration Scripts8. Migrating Directories from Earlier ReleasesWith Red Hat Enterprise Linux, OpenLDAP uses Sleepycat Software's Berkeley DB system asits on-disk storage format for directories. Earlier versions of OpenLDAP used GNU DatabaseManager (gdbm). For this reason, before upgrading an LDAP implementation to Red HatEnterprise Linux 4.5.0, original LDAP data should first be exported before the upgrade, and thenreimported afterwards. This can be achieved by performing the following steps:1. Before upgrading the operating system, run the command /usr/sbin/slapcat -lldif-output. This outputs an LDIF file called ldif-output containing the entries from theLDAP directory.2. Upgrade the operating system, being careful not to reformat the partition containing the LDIFfile.3. Re-import the LDAP directory to the upgraded Berkeley DB format by executing thecommand /usr/sbin/slapadd -l ldif-output.9. Additional ResourcesThe following resources offer additional information on LDAP. It is highly recommended that youreview these, especially the OpenLDAP website and the LDAP HOWTO, before configuringLDAP on your system(s).9.1.
