Issue originally filed as
NIFIREG-133. Filing in NIFI project since addition will be made to the NiFi User Guide.
Original Jira description:
I have a process group PG that contains an embedded process group PG1. I have a variable defined at PG level that is referenced in a PG1's processor. When versioning both PG and PG1 in NiFi Registry, a copy of the variable defined at PG level will be created at PG1 level.
Consequently, when importing PG in another environment, the variable needs to be modified at PG1 level because the one created at PG1 level overwrites the one initially defined at PG level.
> Would be nice to add this behavior in the documentation.
