I need to check the compatibility between MQ 5.3 and MQ 7.0; with the client residing in 5.3 and Server on 7.0.
Is this possible????? (i mean connection between 5.3 and 7.0) |

Have you tried it? Do you have any particular reason for thinking it won't work?
EDIT: I ask as it may be that you do not 'control' the client end, and that this 5.3 client-to-server 7.0 may be imposed upon you.

Upgrade the client already. You upgraded the server...

The reason for asking is that before getting into the upgrade of server from 5.3 to 7.0 and getting the client ready on 5.3; I want to make sure that there should not be any kind of issues regarding the connectivity between the 2 because of the lower and higher end versions. |

| In any case, a WMQ 5.3 client is not supported anywhere. It has reached 'End of Support'. |

Another consideration here might be the use of a Client Channel Table (amqclchl.tab) file. This was mentioned in the webcast today from IBM about MQ v7 migrations:
"Client channel definitions that are written to a Client Channel Definition Table (CCDT) file contain an inherent structure version for each channel. The version of the structure dictates which versions of WebSphere MQ can read the definition. It is not possible to define a client channel in a CCDT using WebSphere MQ V7.0 and have it read by a WebSphere MQ V6.0 client or an earlier version client."
The level 2 person giving the presentation mentioned that if you ever need to change the CCDT for an older client, then you need to keep an older version of MQ around in order to reconstruct it. Best bet is probably to include the upgrade of your client machines to V7 along with the servers, unless you have LOTS of client instances, or don't use client channel tables.
Just my $.02

No true. SupportPac MO72 http://www.ibm.com/support/docview.wss?uid=swg24007769 , includes a stand-alone program which can maintain CCDTs for various versions of MQ.

A 5.3 Client should have no problem connecting to a QM that has been migrated to 7.0 if it was able to connect to the QM when it was 6.0.
|
The issue here is that both the MQ client and Server are currently in 5.3 and the management wants to upgrade the Server from 5.3 to 7.0 |

So, do you not have a test server and client to try it on? To get the empirical information you are obviously seeking?
