Hello!
For testing I often up- and downgrade Bind versions, ie. Between 9.18,
9.20 and 9.21. I wonder how stable the binary zone file format and
journal file format is, and if there are changes in the binary format,
if Bind would detect that and behave properly.
I am concerned about zones that end up containing some garbage. I never
had any issues, but I wonder if that could happen.
Files have version number in their header, so it should be detected and
it should work ... Except for bugs when it does not.
It is rare, but it has happened in the past:
See https://bind9.readthedocs.io/en/v9.16.50/notes.html and search for
"journal" around 9.16.16 and older.
