@phaelax This is very possible and very commonly done. NiFi's Remote Process Group (RPG) is commonly used (recommended method) to transfer NiFi FlowFiles between different NiFi instances or even different NiFi clusters: https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#Remote_Group_Transmission https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#remote_group_anatomy When a direct connection between NiFi's can't be made, you can also use the mergeContent processor to "FlowFile Stream, v3" to merge numerous FlowFiles (includes FlowFile attributes) in to a single FlowFile that can be transferred by any means to another NiFi where it can be ingested and use the unpackContent processor to unplack that into the original FlowFiles with their original attributes.
