Hi, I need to migrate accounts and mail from Zimbra 7.1.x on RedHat EL 4 64-bit to Zimbra 7.1.x on RedHat EL 5 64-bit.

I was able to retrieve the LDAP "Bind password" from the old server...
zmlocalconfig -s zimbra_ldap_password
...but I'm not sure what I should enter for the "LDAP search base" so as to copy everything. I tried (zimbraMailAddress=*) but I get an error...
Message: mail.osubookstore.com Error code: bulkprovision.BP_NAMING_EXCEPTION Method: [unknown] Details:soap:Sender
I have tried both an SSL and non-SSL connection.

Please advise. thanks.

By the way, I cannot simply copy the /opt/zimbra/ folder to the new server because it has a different hostname and ssl certificate, and upgrading from RedHat 4 to RedHat 5.
