   Thanks for reply . The tests are complicated and difficult at one project.  
The process trace detail as follow ：
   
   The client version is 2.4.x whitch has not SessionSendMessage_V2, sends 
SessionSendMessage packet to the server
   
   The server version is 2.12.x , use ServerPacketDecoder.decodeSessionPacket 
method to decode message packet, but the method decode it to SessionSendMessage 
or SessionSendMessage_V2 depending on the connection version whitch has been 
set to server version(2.12.x) after failover reattach.
   
   So the SessionSendMessage was decoded as SessionSendMessage_V2, losing the 
last Long correlationID, causing CoreMessage.decode error.

> Recently we want to update our artemis server from version 2.4.x to 2.12.x, 
> but without updating all client ( too many modules and projects using ). It 
> was OK at starting days, but a few days later,  we received the error in the 
> server's log:

> Old version client (2.4.x  )  send messages to  newer version server(2.12.x) 
> error.
> It also occurs in latest version.
