So the question is simply what are the physical connection requirements to get 2 EVAs to talk to each other? Do I run both EVAs into a SAN switch and zone them together? (generally speaking, targets don't talk to each other, so I am guessing no here). Is there a special back end port for mirroring/migrating? More than 1 option to choose from?
Any specific info appreciated, especially relevant documentation.

Even though you made the zoning between EVAs, you can't do a migration as this is a licensed feature and requires EVA Contineous Access License to migrate the data between EVA(EVA Replication)
If license is there, yes we need to made the zone between EVA host ports so that they can talk to each other and you can create a DR Group(Group of Vdisk that can be replicated to target EVA).
You can dedicate Single/2 ports on each controller for replication. For this you need to do the zone between the Host ports as like below
Zone: EVA8100_CON_A_FP3; EVA8400_CON_A_FP3;
Zone: EVA8100_CON_A_FP4; EVA8400_CON_A_FP4;
Zone: EVA8100_CON_B_FP3; EVA8400_CON_B_FP3;
Zone: EVA8100_CON_B_FP4; EVA8400_CON_B_FP4;
So that source and destination EVAs can talk by using these ports.
You can search for "HP StorageWorks Continuous Access EVA Planning guide" which gives a complete picture about the other dependencies
There are some services offered from HP for data migration

Also, related to the above zoning recommendation, do I have to zone the same ports together, ie: CA/FP1 <-> CA/FP1 or could I do
CA/FP1 <-> CA/FP2
CA/FP1 <-> CB/FP2

Operation Failed! The local storage system has no available path to the remote storage system.
There must be some option in command view, or config step, or something, after the zone is setup, to get the 2 arrays to see each other. Any advice?

I have a HP 6300 EVA and I am trying to replicate to a EVA4400 using CA.
Both SAN's are licensed with CA. Each SAN has 2 controllers with 2 fibre ports.
I have merged Brocade SAN switches and both SAN's appear together in Command View P6300.
When I try to setup a Data Replication group I get an error telling me that there are no remote connections available
Although, on the Data Replication tab in vdisk properties both SAN's are recognised. I can setup the DR group to the point where I get another error "operation failed the local storage system has no available path to the remote storage system"
In terms of zoning, do I need to dedicate one port on each controller or is there something else I may be missing in the configuration?
