Hi, here the step i begin to make a clean migration between ldap(s) with different version of gosa schema :

a ) I export all my users from old ldap + old gosa 2.6.2 into a backup ldif file backup.ldif, b) I create a new openLdap (last release version) on a server wich run with all the new schema for gosa 2.7.1 c) I start with a new bdb which get the data from my backup.ldif :

database config rootdn "cn=admin,cn=config" rootpw {SSHA}...

database bdb suffix "dc=parisgeo,dc=cnrs,dc=fr" rootdn "cn=admin,dc=parisgeo,dc=cnrs,dc=fr" rootpw {SSHA}....

c ) I import the backup.ldif into the new ldap, no problem at this step !

d ) i install the new version of Gosa on apache2, and i configure gosa.conf to connect to this dn ="cn=admin,cn=config" with the good admin password.

At this step i'm not sure, but i think gosa want a specific administrator dn, not THE config dn, can you certify me this point ?

If it's the case, the new LDAP doesn't have the correct ACL and i think i need to import old ACL for specific administrors of Gosa. But i'm not sure, it is possible to use the cn=config access to use with gosa ?
