Re: Problems with NiFi Registry Conflicts after Processor Upgrades
Chad, I wanted to echo Bryan and say thanks for sharing the details of an upgrade process that works. Until we have improved NiFi to handle the upgrades regardless of order of steps, this is a helpful reference for the community for a sequence that can work.

Re: Problems with NiFi Registry Conflicts after Processor Upgrades
Chad, Thanks for reporting your experience and glad to hear that there is a good process to follow. We do want to make this situation better and there is a JIRA to track the issue [1].

Re: Problems with NiFi Registry Conflicts after Processor Upgrades
Hey guys, I'm going to be upgrading my NiFi clusters to 1.9.1 soon so this topic was important to me. I've done some testing and wanted to share my results. *Test environment setup*: 2 NiFi Clusters 1 NiFi Registry Dev NiFi on 1.8.0 versioning flows with NiFi Registry 0.2.0 Cert NiFi on 1.8.0 versioning flows with NiFi Registry 0.2.0 *Working upgrade method*: 1. Upgrade Dev NiFi from 1.8.0 to 1.9.1 2. All Dev NiFi versioned flows showed local changes due to new properties in processors 3. Commit all Dev NiFi changes for all versioned process groups 4. In NiFi Registry, view and see all committed changes from Dev NiFi 5. On Cert NiFi, all versioned PGs show newer version available. 6. On Cert NiFi, change all versioned process groups to use new version. PGs now show "Flow version is current" (Note: the processors DO NOT become invalid and they do not show the new properties yet) 7. Upgrade Cert NiFi from 1.8.0 to 1.9.1 8. On Cert NiFi, all versioned process groups still show they are on the latest version and the processors DO show the new properties now *Not working upgrade method*: 1. Upgrade Dev NiFi from 1.8.0 to 1.9.1 2. All Dev NiFi versioned flows showed local changes due to new properties in processors 3. Commit all Dev NiFi changes to all versioned process groups 4. In NiFi Registry, view and see all committed changes from Dev NiFi 5. Upgrade Cert NiFi from 1.8.0 to 1.9.1 6. On Cert NiFi, versioned process groups show "Local changes have been made and a newer version of this flow is available". When clicking on PG and selecting "Version", only options are "Show local changes", "Revert local changes", and "Stop version control". "Show local changes" allows you to see what has changed (all new properties in processors). "Revert local changes" does nothing as these changes are required since they are new properties from the upgrade. 7. My only 2 options at this point are -Stop version control of the PG and start it back up, causing me to lose all history -Delete the PG on Cert and then re-import from NiFi Registry. This option really isn't an option when in Prod as I don't want to stop/delete production flows that need to keep ingesting data. So as shown above, when upgrading NiFi with versioned flows in NiFi Registry, the steps are very important and as long pull in the latest commit to Cert before upgrading Cert, your process groups will work as expected.

Problems with NiFi Registry Conflicts after Processor Upgrades
Ran into a NiFi Registry issue while upgrading our instances to NiFi 1.8.0. ExecuteSQL had a number of new properties added to it in 1.8.0, so after upgrading our, our versioned processor groups show as having local changes, which is good. We went ahead and checked the changes into the registry. Enter the second instance... we upgraded a second instance. It also see's local changes, but now the processor group is in conflict, because we have local (identical) changes, and we have a newer version checked in. If you try to revert the local changes so you can sync things up... you can't, because these are properties on the Processor, and the default values automatically come back. So our second processor group is in conflict and we haven't found a way to bring it back in sync without deleting it and re loading it from the registry. Help would be appreciated. Thanks, Peter
