Workarounds and Mitigations


Support for IBM MQ CloudPak versions
The support lifecycle for IBM MQ CloudPaks is tied directly to the support
lifecycle of the IBM MQ version that runs within the CloudPak. When the
underlying MQ version goes out of support then the CloudPak will automatically
go out of support. IBM MQ CloudPaks are only available with Continous Delivery
versions of IBM MQ and so follow the IBM MQ Continuous Delivery support
lifecycle .
The version number for the CloudPak provides an indication to customers on what
kind of change has been made between different versions. The versioning system
used in CloudPaks is the semver versioning system and does not correlate
directly to the V.R.M.F version used by IBM MQ.
For reference the table below shows which versions of IBM MQ are available with
which version of CloudPak, this can be used to determine whether the version of
CloudPak you are using is still in support:
                      IBM MQ CloudPak and IBM MQ versions
| IBM MQ  |  IBM MQ CloudPak for IBM  | IBM MQ CloudPak for IBM Cloud Private |
| Version |   Cloud Private Version   |      on RedHat OpenShift Version      |
|9.1.2    |3.0.0 and later            |2.3.0 and later                        |

|9.1.0    |2.0.0 - 2.1.0              |2.1.0                                  |
