@abhinav_joshi You should have been able to right click on the "Ghost" processor and select "change version" option. This would have presented you with all the available versions in your NiFi installation. Simply select the one you want to use would resolve your issue. While this work great when you only have a few ghost processor created from your dataflow, it can be annoying to follow these steps for many components. The question here is why does you deployment of NiFi have multiple versions of the same NiFi nar installed. NiFi would not ship this way, so that means that additional nar(s) of different versions where added to your NiFi lib directory or to the NiFi extensions directory. You should remove these duplicate nars to avoid running into this issue again. When only one version exists, dataflow imported/loaded with older versions will auto switch to version used in the NiFi in which dataflow was loaded (this may mean and older or newer version of nar classes).
