Hi,

I'm decomissioning a mail server and moving its operations to another. The old server is running 0.9.9 and the new server is, too. Both are running the LDAP back-end. The old server has the hostname (for example) vs109.mydomain.com, the new server has the hostname mx.mydomain.com. There is also an A record pointing to vs109's IP and is used as an Apache virtual server and the hostname for mail users' interaction with the server.

I am at the point of restoring an LDIF on the new server. The LDIF includes lots of domain components sharing parts of the hold hostname - dc=vs109,dc=mydomain,dc=com.

Can I restore this file without making any changes, or should I change all "dc=vs109" records to "dc=mx" prior to restoring on the new server? If I do restore the LDIF without making any changes, will there be any issues with ongoing management? I'm not at all familiar with LDAP behaviour.

Thank you!
