Re: (ITS#9056) Replication does not work with different schemas on primary and secondary LDAP

Ciao, Michael

I understood the risks but how can I resolve my issue?
My case I want to upgrade all servers step by step without lost data on =
secondary LDAP servers

For now when I add the new attribute to some item in LDAP then this item =
lost on secondary servers.
Moreover, replication stops after receiving the first item with unknown =
data. So, I will lose not only one changed item and also all next

I have a few hundred of LDAPs servers which should be updated one-by-one =
and in this case, I will lose the data until upgrade all of them

Thank you in advance.
Best regards, Alex
