I've migrated around 300 users from a Fedora server to Ubuntu. I copied over all the relevant entries in
/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?
