Okay, you have these in your smb.conf:

         workgroup = MY.DOMAIN
         passdb backend = ldapsam:ldap://ldap2.my.domain

You have this error message:

Failed to connect to ldap URL 'ldap://ldap2.MYDOMAIN' - LDAP client

Is this bad sanitisation ?

Does the workgroup 'MY.DOMAIN' actually have a dot in it ?
Why is the upgrade reading 'ldap2.my.domain' as 'ldap2.MYDOMAIN' ?
Is the old ldap server still running and accessible ?
Can you post the ldap object for 'Domain Users'
What is the DNS domain name of the computer you are running the upgrade
