@vystar  Considering the breaking changes that are part of Apache NiFi 2.0/1, there is considerably more work in preparing for an upgrade to the that new major release.  So I would recommend upgrading to the latest offering in the Apache NiFi 1.x branch.   You'll want to review all the release notes from 1.13 to the latest release: https://cwiki.apache.org/confluence/display/NIFI/Release+Notes/#ReleaseNotes-Version1.12.0 You'll want to pay close attention to any mentions of components being moved to optional build profiles.  This means that these nars and the components they contain are no longer include with the Apache NiFi download and if needed must be downloaded form Maven Central and manually added to NiFi.   Deprecated components still exist in the Download, but will not exist in NiFi 2.x releases. Make sure to maintain a copy of your flow.xml.gz/flow.json.gz (newer releases).  The newer Apache NiFi 1.x load a flow.json.gz instead of the older flow.xml.gz on startup.  However, in the absence of a flow.json.gz and the presence of flow.xml.gz, NiFi 1.x will load from the flow.xml.gz and produce the new flow.json.gz. After upgrade, you'll still need to review your dataflows.  There are some bad practices that are now blocked by Apache NiFi that may leave some components invalid until manual action is taken to resolve the bad configuration (such as using "primary node" execution on any processor that has an inbound connection). As far as FlowFile distribution, do it early in your dataflows as possible. Utilize list/fetch still processors instead of get style. (Example: use ListSFTP and FetchSFTP in place of GetSFTP.  This allows you to load-balance the 0 byte listed files before the content is fetched for the files). Other options like Remote Process Groups can be used (they come with some overhead, but do some target NiFi Cluster load based distribution when dealing with large volumes of FlowFiles.  Not so great for low volumes.).   Please help our community thrive.
