9.11 -> 9.16 via COPR

John Thurston
We're happily running the BIND 9.11 ESV on CentOS 7 by way of:
   isc-bind-esv/x86_64 Copr repo for bind-esv owned by isc

The roadmap I recall indicates 9.11 will move to "security only" updates
at the end of 2020, at which time 9.16 is slated to become the ESV. I
figure it is time for me to get a 9.16 instance running and see what
will be involved in making it work for us.

My questions are two:
A) How will the upcoming change in ESV-designation appear to users of
the COPR packages? Will there come a time when the repository/package
"isc-bind-esv" will just deliver 9.16 rather than 9.11?

B) If I have a host currently using "isc-bind-esv/x86_64", and I want it
instead to use "isc-bind/x86_64", what's the suggested process? Do I
"yum remove", replace the "bind-esv" repository with "bind", and "yum
install"? Is it simpler than that?

Do things because you should, not just because you can.

Correct.

Good call :)

This is what we currently _plan_ to do, but I would not like to make any
particular _promises_ at this point yet.  Things should become more
definite around the end of the year.

I would personally just add the "bind" repository and run "yum update",
there is no need for a "yum remove" here.  Unless your configuration
contains statements which prevent BIND 9.16 from starting up, this may
be all you need to do to perform the upgrade and it should be fairly
seamless (though prior testing is of course strongly recommended when
updating across major versions in a production environment).  The most
recent BIND release in the "bind-esv" repository should never be newer
than the most recent BIND release in the "bind" repository.

Hope this helps.  Feel free to let me know if you have any further
questions on this subject.
