I do the following :
export the users from production server with lat admin tools, using
lat-dump.
Install new server on new hardware.
copy the exported files from production server to new server.
Import all accounts, ibays, groups, etc.. on ney server, again
with lat admin tools with lat-users command.
Copy shadow, smpassword, gshadow, to new server (if you want
the same password to users accounts).
Now you can copy the /home/e-smith/files/users directories from production server to new server.
For me the problems that I have is migrating application
like RT Helpdesk from
www.bestpractical.com, i need to re-install again.
