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:

https://kb.isc.org/docs/changes-to-be-aware-of-when-moving-from-911-to-916

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.
