We have IIB 9.0.0.7 running in our environments.

We are planning to migrate from 9 to either 10 or 11.

What would be the better option.
9 to 10?
or
9 to 11 diretcly?


I feel its better to go with stable version of 10 rather than going for most latest version.

Any Thoughts?

Then you should do that. Seriously.

The decision is based principally on your site's appetite for risk, how quickly your site upgrades, how disruptive the upgrade will be at your site, etc. etc. There's no right or wrong answer, just the right answer for you.

FWIW my site planned to move from 9 to 10 for what sounds like similar thinking to you. Then we got into the planning, the migration strategy, the testing and management said:

Quote:
Contact admin this! We're not doing this to go to 10, then do it again in a year or two to go to 11! The customers don't have time to do two tests! We'll take the risk, go straight to 11. And we'll build it on RHEL 7 not 6, so that'll save another migration. So that means we can use MQv9.

Still doable by the end of 2019 though, yes?


So glad I don't sit near the platform engineering team any more.

The point being, typically risk is a top priority here. Having weighed it, we went a different way. I don't think that's wrong and the platform people have lots of automation to help them........

Do the consuming applications have to re-generate their stubs for SOAP services over IIB9, once we migrate from IIB 9 to 10 or ACE 11?

Does IBM recommend to must re-generate stubs for existing SOAP services built in IIB 9? Will they face any issues if they don't re-generate their stubs and hit same SOAP web services which now running on latest version?
