# TEST	rep011
# TEST	Replication: test open handle across an upgrade.
# TEST
# TEST	Open and close test database in master environment.
# TEST	Update the client.  Check client, and leave the handle
# TEST 	to the client open as we close the masterenv and upgrade
# TEST	the client to master.  Reopen the old master as client
# TEST	and catch up.  Test that we can still do a put to the
# TEST	handle we created on the master while it was still a
# TEST	client, and then make sure that the change can be
# TEST 	propagated back to the new client.
