Cent OS migration

[scooter6 at gmail.com]

Okay - the time is approaching where we're going to switch from SCO
OpenServer to CentOS.
I have a few questions.

1.  Is there a migration tool that will take all my existing users and
'import' them as users on CentOS?
2.  Does anyone have suggestions on specific hardware to use? We are a Dell
shop if that matters.....
     i.e.  How much RAM are people using on CentOS? (we have approx 60-75
users on during peak hours during the day, lots of processes running, etc
and we have
            several larger files that we run re-indexing on over weekends -
currently, this takes about 18 hrs on our current system)
3.  Is setting up printers/drivers pretty simple on CentOS?
4.  What RAID configuration is best for speed and failover, etc?  We are a
busy place and can't afford downtime.
5.  Can you run a backup to a USB drive using CentOS? If not, what backup
solution is best?
6.  Does CentOS support dual processors?
7.  Is there a specific version of CentOS that seems to be more stable, etc
than others?
8.  Other than exchanging our current licensing with filePro, is there
anything else that needs to be done to the filePro files so they run on
CentOS?
9.  For my many scripts that I have running, is there a big directory
hierarchy difference on CentOS vs. SCO?
     i.e. are user profiles still in /usr directory? Does the PATH variable
need to change on my scripts? i.e. /usr/bin, /usr/local/bin, /etc, etc

I'm sure I'll have more questions, but this is a good start.

Thanks for any suggestions and/or input.
