   @avgAGB We occasionally add features to RFiles that make it support things we add to Accumulo. Those changes won't be understood by older versions of Accumulo, but they don't typically alter the fundamental storage concepts of RFiles. I believe the main feature added after 1.10 was the ability to support data emitted from a configured Sampler.
   
   If you need to extract data from one RFile version and store it in an older Accumulo version, you could just create a scanner and scan the data in the file, storing it in whatever intermediate format you wish.
