A similar issue is still observable when the old store has queues defined in it.

> A recent checkin (r.831082) fixed a problem in which the exchange did not persist the
alternate-exchange setting, and on recovery this was being lost. To fix it, an additional
string was added to the Exchange::encode() and Exchange::decode() methods. However, this fix
means that there is a binary incompatibility between pre- and post-fix exchange data. Attempting
to recover stores from pre-fix brokers result in broker shutdown if recovery is attempted
using post-fix brokers.
