JMS Mix "Classic" Clients with "Artemis" Servers

[Christoph Läubrich]

We currently plan to switch from Classic>Artemis but there is one point 
not completely clear (or I have missed something?), is it possible to 
connect with a "activemq classic" JMSConnectionFactory to an artemis 
server (given that they both enable the tcp transport of course, same 
host and port etc...)

So we can switch the server to "Artemis" and then upgrade the (classic) 
clients step-by-step?
