ArcGIS Server License for FME Fow

When FME Flow connects to ArcGIS (SDE), ArcGIS server must be installed AND licensed on the same FME flow Engine service machine. The ArcGIS version must be compatible with FME: Notes on FME and Esri Versions and Compatibility.

More information on using FME Flow with ESRI ArcGIS software is available in this link

It is hard to give a correct response on this, because legally you are only allowed to install FME server and ArcGIS Enterprise on the same machine.

It is technically possible to install ArcGIS Pro with a standalone license on the same machine as FME server, and I have seen posts where users were told (not by Safe employees) the were allowed to do this as they already had Enterprise installed.

The link above states the following about fme flow being able to read esri formats:

There are a couple of options here.

One is to install a FME Flow Engine on the ArcGIS Server host. Then route the Esri jobs via a separate FME Flow Queue to the remote Esri Engine.

The second option is, if applicable, to use the Readers/Writers for Esri ArcGIS Portal (or Esri ArcGIS Online) Feature Services. Then you don’t need a Esri Server license, i.e.you can run the FME Engine on any host available. However, for bulk loading large datasets I would go with the first option.

@harish I think you’ll find my answer had the link/answer to the above knowledge base article about requiring FME server license on Flow.
