I have run the DB Verifier from the ZCM 11 install DVD proior to doing the upgrade and it completes ok but with warnings, do I need to do anything with them?

Warnings (x4) are all related to 'Extra object in table 'zLdapSource', the object names are ipAddress, UseSSL, SSLPort and CleartextPort.
Does anyone else see these warnings, can I proceed with the upgrade anyway?

Upgrading from 10.3.3 on win2003 running on vmware ESX, internal DB, AD only not edir.
