I currently have a Linux box hosting our internal Subversion repository. Access to this repository is via svn+ssh with authenticating happening against user accounts on the machine. I have recently acquired a shiny, new box (also installed with Linux) and want to transition the subversion repository across to it (as it has more space across six disks configured using RAID 1+0).
What do I have to do to transfer all the user, group, and file information from the current machine to the new machine so as to minimise the impact on the current users of the repository? My current thoughts are to copy across the relevant entries from the /etc/passwd and /etc/group files (and shadow files?), and to copy the user folders in /home. Is there anything I am missing?
EDIT: Extra info. Old box is Ubuntu 8, new box is Ubuntu 9. There are about a dozen users and a dozen custom groups.
