That's a bit loose, and forgot a dash. The following should really only get 
the uid's (not the gids, parts of a password, comments and what not):
for uid in $(jot - 2001 3000); do \
	grep -E "^[^:]+:[^:]+:$uid:" /etc/master.passwd;
done

This doesn't migrate home dirs, but using the above and piping to:
	cut -f 9 -d ':'
should give you a list of home dirs to work with.
