Hi Vijay,
 
We’ve upgraded directly from 1.28.1 to 2.6. It worked, but at first the server wouldn’t start correctly. We had to mess around with some renamed controller services
 and nar bundles (for example using DistributedMapCacheClient/Server to MapCacheClient/Server).
According to Jira, those breaking changes happened in 2.0.0 already (https://issues.apache.org/jira/browse/NIFI-13596)
 so I don’t think you’d have a smoother upgrade by going to 2.0.0 first. 


Btw, 2.7 was unusable to us because of memory leaks in the DBCP connection pools. We went for 2.6 instead, but it should be fixed in 2.8
https://issues.apache.org/jira/browse/NIFI-15372
 
Kind regards,
 
Isha

One more question for migration, do I HAVE to migrate to 2.0 first and then to 2.7.2 ? 

Thanks

Hi Stefan,

Once you’ve upgraded to 2.0 you should be able to upgrade directly to 2.7.2. There are some changes and deprecated features you should be aware of, you can find more information in the NiFi release notes:

Hello Group,

We are looking into upgrading from 1.28, and I know that I need to go from 1.28 to 2.0, but if we want to go on from there, can we go for instance from 2.0 directly to 2.7.2? Or do we need to “stage” the upgrades more?
