Inside nested process group set up ConsumeJMS and/or PublishJMS processors with "Connection Factory Service" setting set to "JMSConnectionFactoryProvider" (and any other settings). In my environments I have the proper controller settings installed as well.
Start version control via NiFi Registry.
Move to alternate environment
Create process group and import from Registry
Go into nested processor group and find the settings have been cleared. One needs to set the one Connection Factory Service setting to make the processor functional.
