[CentOS] Moving a Centos 3.5 instalation with software raid 1 array + LVM from a pIII to a pIV computer.

Hi All,

We have an old Centos 3.5 file and database server, running on a pIII
computer with Intel 820 mother board. It has a software raid 1(mirror)
+ LVM on two IDE hard disk.

I want to upgrade to a newer computer with pIV - 2.4GHz on a Intel
D848PMB mother board.

Should I expect any problems if I just move the array from the old
machine to the new and boot there?

Should I do any preparations(I know I must do a full backup), before
moving the disks?

Best regards!
