----------------------------------------------------------------

Please add this feature, preferable in a point release and not in a too distant future.  This is painful experience.  I have flows that I re-use for different data sources/targets, which I previously used variables to configure.  When I copied the process group, the variables would copy and I could then change them as needed.  Now, I have updated then to use parameters, which I find more useful especially for sensitive values and for processor/controller properties that do not support Expression Language.  Unfortunately, now that the parameter context is separate from the process group, I have to manually create a copy of the parameter context, which has 56 parameters.  

You could add a copy/paste function to the NiFi Parameter Contexts window, add a 'Save As' to the Update Parameter Context window, or have an export/import feature allowing you to save/load the parameters to disk, possibly in a json format.

Note, I would expect a copy/export feature would copy all parameter values, with the exception for any sensitive parameters.

BTW, I found mentioned in related feature proposal this copy feature, "When creating a new Parameter Context, the user should be given ability to create a new, empty Context or copy an existing Context that they have READ permissions to. This makes it far easier to design a flow, then deploy several instances of the flow, in which each instance has mostly the same parameters but slightly different."  See https://cwiki.apache.org/confluence/display/NIFI/Better+Support+for+Parameterizing+Flows
