No, you should not overwrite them if they contain the host keytab.

If they are ipa clients and you can install admin tools you can simply
run the ipa-getkeytab command on the right machine directly.

if you can't for whatever reason you should copy the new keytab to the
machine in a temporary (but protected) location like /root/nfs.keytab

Then use the ktutil tool to merge the 2 keytab files
into /etc/krb5.keytab

ktutil is not the most intuitive tool, but the documentation should be
good enough to sort out what you need to do.

Simo.
