Variables disappear from nifi 2.x

[e-...@gmx.fr]

Hello. 

How to deal with processors groups with “variables” when we migrate from 1.x to 2.x ?

For now I have tried to migrate from 1.28 to 2.10, but all my processors groups failed cause by missing variables. 

Thanks for helps.

Variables have been replaced by Parameters in NiFi 2, which can be provided
by Parameter Contexts. This is a much better, hierarchical organization
with many powerful features in NiFi 2 such as Parameter Providers. To
migrate you would want to convert the variables into parameters, associated
with either a top-level Parameter Context, or even better creating
Parameter Contexts that are hierarchical so each Process Group (PG) so each
PG only "knows" what it needs to know.

Matt
