do we need to have MQ v7 client in order to connect to two or more IP’s for multi-instance QManagers ?
Thanks |

More information about what? Using clients in an MI situation? The fact that WMQv6 clients don't support MI?
Both of those are answered in the v7 documentation.

so if we are moving to MQ V7 all the clients/App's connecting to the Qmgrs(V7) needs to be changed to V7? |

No, but a sensible thing to do anyway if you're moving to WMQ V7.0, and yes if moving to MI queue managers.

If and only if you're plannning to use the new-to-v7 MI feature.
If the queue manager is (for example) protected by HACMP and does not use MI then a v6 client can connect to a v7 queue manager just fine.

Depending on the client language, and whether LDAP is in use, SupportPac MA98 could suffice.

we will be using MI for the Qmgr but the thing is the client is not directly connecting to the Qmgr
ex :
QMI(Client side)....(using VPN).....> keeps message to QM2(our side which is in dmz).......(Puts message to another Qmgr)....>QM3......>QM4......>QM5(we will be changing to MI).........>(App on our side).
in this scenario also do we need to change the client to MQ V7? |

We and Client are using Java Programs and i am not sure about LDAP. |

The SupportPac becomes irrelevant in this case. The client side does not need to be V7.0 (from the diagram in your previous post) but it would be sensible to upgrade it to the same level of WMQ as the queue manager.

This picture is NOT the same as "connect to two or more IP’s for multi-instance QManagers ? ".
That picture would have QMI(client side)->QM5, with nothing in between.
But be aware in your picture if QM2->QM3->QM4 is an MQCluster, then you DO need MQ v7 on all those machines if you change QM4->QM5 to MI link. |

So if QM4 is connecting to QM5(MI) so there is no need of QM4 to be in MQ V7 and just the channel to be (ip(port), Ip(port) ) like this?
and Qm1 which is Client side qmgr should be in MQv7 too or not
and QM2->QM3->QM4 these are not in clustering. |

QM4 NEEDS to be MQ v7.
None of the others *need* to be MQ v7. UNLESS they are in an MQ Cluster with AT LEAST ONE MI qmgr.
All the others *should* be in MQV7, as soon as possible. |

Any queue manager connecting to an MI queue manager needs to be able to address both IP Addresses/DNS Names of the servers on which the MI queue manager can run, and the best way to achieve that is for the connecting queue manager to be V7.0.

No, not if it's not connecting to an MI queue manager but it's worth your while upgrading everything to V7.0 anyway.
