We recommend to users contemplating moving from the EOL BIND 9.11 branch 
to the BIND 9.16 branch that they read the following document:

With the January release of BIND 9.18.11, we are now designating the 
BIND 9.18 branch an Extended Support Version (ESV). Users of 
ISC-packaged BIND please note that we are not yet changing the version 
of BIND provided in our Cloudsmith and COPR repositories; these will 
remain the same until BIND 9.20 is published, at which point we will 
announce the rollover of the repository contents.

We have also published a new document covering differences to be aware 
of when migrating from the BIND 9.16 branch to the BIND 9.18 branch:

https://kb.isc.org/docs/changes-to-be-aware-of-when-moving-from-bind-916-to-918

Users migrating from EOL BIND 9.11 branch directly to BIND 9.18 
(bypassing BIND 9.16) should look at both the "changes to be aware of" 
documents linked above.
