You should be concerned only if you are operating a DNSSEC validating resolver 
and that your clients are using this resolver to do DNS resolution.
i.e. in your BIND configuration:

dnssec-validation auto;

If so, you are probably using managed-keys in bind, you can do the verification 
by running a RNDC managed-keys status, you would see the new key marked as 
‘added’ after July 2017 publication.

After 11 October 2018:
Be on the lookout for DNSSEC validation failures when the key in use changes to 
the new key.

However, if you are running authoritative services with BIND, or a resolver 
that is not doing DNSSEC-validation, you should not see an impact.

Hope that helps.

Regards,
Amreesh
