[K12OSN] Upgrade from K12LTSP 4.2 to 4.4.1 how to transfer SMBLDAP info

[Krsnendu dasa]

I currently have a K12LTSP 4.2 system running with SMBLDAP providing
authentication and homes users on LTSP client computers and windows
machines.
I decided I wanted to try out Crossover Office 5 (but not on the current
production server), so I have installed K12LTSP 4.4.1 on a new box and
installed Crossover Office 5. What do I have to do now to set up SMBLDAP and
transfer all the user authentication info to this new box so it can become
the official new server and I can use the other server for other purposes.
I have gigabit connection between the servers, so copying files is pretty
quick.
