I've done this many times but always from root.
With no root account, I would:
1) create a 2nd user 'test', set a password, and make 'test' a sudo user
2) logout and login as 'test'
3) let's say the user to change is 'bob' with id 1000
grep bob /etc/passwd
should yield:
bob:x:1000:1000:Bob:/home/bob:/bin/bash
4) edit /etc/passwd and change the 1st number (the uid) for 'bob' from 1000 to
54321 and save
5) run:
sudo find / -xdev -uid 1000 -exec chown bob {} \;
-xdev says stay on this filesystem; don't descend into /proc or /sys or /cdrom and
so on.
This could take awhile.
6) logout from 'test' and login as 'bob'
HTH,

Hi,
I am on a single-account F27 system with an user id 1000. I want to change this user id.
From what I understand, I should do the following:
sudo usermod -u 54321 <username>
However, when I do this, I get:
usermod: user <username> is currently used by process 866
I guess that this has to do with the fact that I am logged in (to do this). How do I get
around this point? There is no root on the system but I do have sudo access.
Separately, I want all my files and directory owned by 1000 to move to this user id (so
that I can have access)? Is this automatic or do I have to run chown -R <username>
etc?
Many thanks and best wishes,
Ranjan
