[K12OSN] Bringing /home over from previous k12ltsp server

[Carl Keil]

Hi Folks,

I'm setting up a brand new k12ltsp server to replace my previous one.  
What's the best way to bring the /home directory over so that people's 
work in tuxpaint, mail messages, open office docs,  game settings, etc. 
get brought over, but I still update/upgrade all the conf files and 
stuff that are in people's /home directories. 

I was just going to install k12ltsp, then rsync over the old /home into 
the new /home from the old server to the new, but that doesn't seem like 
it quite cuts it.  Like that would overwrite identical files fairly 
randomly, wouldn't it?

Can someone recommend a workflow for this?
