NFSv4 ACLs with rsync

I am looking for a method of syncing NFS directories (Netapp qtrees) that
contains NFSv4 ACLs. We copy qtrees (millions of files, xx TB) from one
qutree into another one.
The only tool we currently use is (netapp internal) ndmpcopy, it preserves
ACLs but is slow.
Netapp "xcopy" tool is also not aware of NFSv4 ACLs.

rsync that is aware of NFSV4 ACLs would be a smart solution for this

I found a discussion and patch in the archive:
"Richard P Sat, 09 Jun 2012 14:19:48 -0700: This is a PoC patch for

​but I did not found any followup​.
Also current rsync 3.1.2 seems not to be able to copy nfsv4 acls (I tested).

Questions Is there some rsync patch or version available that copies nfsv4
ACLs ? Any other Ideas ?
