Transportable backups are only needed if you need to restore it on a
platform of different endian/alignment. The question is therefore
about whether you can safely backup an ODS 10.1 database using
Firebird 2.

I am not aware of any specific reason that this is problematic, but to
be on the safe side follow the letter of the law.

And please make sure my comment is left in context with its attached
warning. This warning still applies to the method described in the
release notes:

" (of course test it yourself first and as always don't bomb the old
database until you are sure the new one worked)."
