Hi,
Yes 5773 to 5874 SRDF is possible.
See Knowledgebase article emc211857 for more information.
At your code levels it would be recommended to update.

Hi,
Fair enough, it may not be clear but my understanding of "Full Support" is bidirectional with the functionality of the lower code.

Steve,
my clarification was whether VMAX-1 (5874) to (DMX4-24 (5773) possible?

Hi Wishtober,,
SRDF replication is possible only if both Symmetrix have same Enginuity Microcode level, but On the EMC support Matrix SRDF is possible if DMX has 5773 and VMAX have 5874. So for your question the answer is YES, Symmetrix Remote Data Facility Replication is Possible ...
R22 volumes must reside in a Symmetrix VMAX system running Enginuity version 5874
or higher. The R11 and R21 volumes can reside in a Symmetrix DMX system running Enginuity
version 5773.

that table does not have anything that talks about SRDF compatibility between different enginuity versions. I have SRDF/S that works with the version i mentioned above. I just want to make sure people who read this thread don't get confused by statements that SRDF only works between same code revision.

Dynamox you are right
I got this info on SRDF Product Guide.
I am talking about SRDF/Synchronous.
please find the attached table. It shows the SRDF group support .

R22 concept looks strange to me. why any one keep BOTH R2 devicestargets on the same array.?

SRDF/S and SRDF/A are supported between different enginuity also. SRDF from older Enginuity (like 5671) to newer enginuity may not give you complete SRDF solution but you should be able to perform data migration using SRDF.

R22 devices are a form of concurrent RDF device. They have two R2 relationships, only one of which can be active at a time. The main purpose of R22 devices is their use in SRDF/Star configurations.
They make Star more resilient and easier to reconfigure after a failure.They can also be used in cascaded SRDF configurations when the R1 site fails and production is moved to the remote site.
