Is it possible to swap personality of devs in SRDF split mode

I have two DMX-3. Both are connected using SRDF sync. From one DMX we have allocated LUNs to prod server which are currently as RDF1. From another we have allocated to DR which are currently RDF2.

The LUNs under concern are currently in SRDF split mode.

The customer wants us to swap the personality of the LUNs. He wants to sync RDF1 from RDF2.

So in current situation is it possible to swap the personality of LUNs and then establish the SRDF.

Any suggestion would be most welcome and helpful.

Thanks in advance.

This information is documented in the EMC® Solutions Enabler Symmetrix® SRDF Family CLI available on support.emc.com;  Check out the Table 55 SRDF control operations and applicable pair states;

Edit: As table shows, Split State is supported, but Footnote 43 applies here which states that it is not supported if consistency is currently enabled.  You need to do symrdf -g group disable if you have consistency enabled.

You can perform a swap while in split mode.
