I've migrated around 300 users from a Fedora server to Ubuntu. I copied over all the relevant entries in /etc/passwd
, /etc/shadow
, /etc/group
, and /etc/gshadow
. One thing that was a bit concerning is that Ubuntu starts the uid's at 1000 while Fedora at 500. I saw that I can adjust that starting number, but will that really cause any issues if I just leave it?
None of the users I copied over had conflicting uid's or gid's with what was already on the Ubuntu server.
I'm wondering if there is anything else I should look out for here. Maybe something that useradd
does that I haven't taken into account?
