It is not a corruption, but the distinction doesn't matter much to the
end user who wants to get the job done with the data right now.  The
data that was made inaccessible is inaccessible.  The only difference is
that it is recoverable once the user upgrades, but that may be painful,
even though it may be rewarding afterwards and worth doing so, and the
user may not be able to afford doing so right at that moment.
