I *hope* you/they mean the /home partition and not the /usr partition,
it's the /home partition that has users' home directories (and
configuration) on it.

It's perfectly possible, all you need to do is edit the /etc/passwd
file so that the user ID and group ID match those you see on the files
in the users' home directories in /home.  At least that's how I'd do
it (being a command line junkie).

Actually now I think about it you can probably do it when you add the
users to your new installation, depending on the tool/utility you use
to add them you may be able to set the user ID and group ID when you
create them.

Ask for more help if you don't understand what I'm on about, it's
always difficult to gauge how much someone knows.
