uid's 100 - 999 are reserved for the packaging system/daemons etc.
you won't likely have a problem but it would be better to migrate to
debian policy anyway.
you can just write a small awk script to take the accounts from your
redhat system (delete all of redhat's system accounts/groups before
running it) to create all the users with proper UIDs on debian, just a
quick not thought out script:
for i in `awk -F: rhpwd '{print $1}'`
do adduser --no-create-home --gecos "$(grep ^$i rhpwd | awk -F: '{print
$5}')" \
--home "$(grep ^$i rhpwd | awk -F:'{print $6}')" $i ; \
chsh -s "$(grep ^$i | awk -F: '{print $7}')" $i
done
another method would be to use sed to change the uid/gid.
if you extract the home directories after creating the new user
accounts they should get the new ownership properly as GNU tar is
fairly smart about this sort of thing.
