  • 1.  IBM MQ client version 8 compatibility with IBM MQ 9.3

    Posted Tue October 22, 2024 01:16 PM

    Hello,

    is it okay to upgrade queue manager to version 9.3 and continue to be working with IBM MQ client version 8? 

    thanks

    If you are using TLS you might run into trouble. I don't believe the ciphers for TLS 2.0 already existed when version 8 was built.

    Outwith the comment already made about TLS - yes, you can certainly use a client at V8 with a queue manager at V9.3 - the protocol used by channels (clients and qmgr-qmgr) expects the two ends to be at different versions and negotiates the differences accordingly.

    Cheers,

    The above link is the IBM Documentation on this topic, with answers to questions like:
    "Are MQ 7.0, 7.1, 7.5, 8.0, 9.0, 9.1, 9.2, 9.3 and 9.4 compatible with previous versions?

    Can a recent MQ 9.4 client (for example) use a CCDT created with a previous version?
    Can an older MQ 9.2 (for example) client use a CCDT created with a newer version?
    Can a JMS .bindings file created in 9.2 be used with 9.4 (for example)?
    Can a JMS .bindings file created in 9.4 be using with 9.2 (for example)?
    Can an older MQ client using an old SSL protocol still work with MQ 9.x?"
