I'm digging through documentation trying to find the right way to activate DSE for RDFGs on a VMAX 400K that replicates to a VMAX 20K. I seem to be finding a combination of conflicting and incomplete information on the formatting of commands for the VMAX3 side of things. Is there any documentation anyone is aware of that is specific to this situation?

There is a LOT of info out there for this (and I have experience with this) on the VMAX2 and earlier arrays, but the VMAX3 does it different and it isn't clear to me what will and won't work. I really need to know this before I start trying it out as I have no test environment.
