Help upgrading from dcm4chee 5.28 to 5.33 without losing existing LDAP configuration

[Andreiver Mateus]

Hi everyone,

I'm upgrading my dcm4chee installation from version 5.28 to 5.33.

In version 5.28, I was using the default LDAP (dcm4che-ldap) and Keycloak (18.0.1) setup, and I have some important configurations (users, roles, groups) already stored in my existing LDAP.

The new documentation for version 5.33 recommends using:

• dcm4che-ldap:2.6.7-33.0

• Keycloak:25.0.5

However, I would like to upgrade without losing my current LDAP data.
I’ve exported the LDAP data using ldapsearch to a .ldif file and I’m planning to import it into the new LDAP container. But I'm not sure if this approach is compatible with the newer version of the LDAP image used in 5.33.

Questions:

1. Is it safe to restore the old .ldif into the new dcm4che-ldap 2.6.7-33.0?

2. Are there any schema or compatibility changes I should be aware of?

3. Is there a recommended migration path to preserve my LDAP users and roles during this upgrade?

Thanks in advance!
