How can I move the pair RDF and BCV to another group

Dear All,

I want to move pair SRDF group and BCV to another device group. May I know the step ?

 

Split the SRDF of device group 

Umount the file system on solaris.

symmir –g cancel BCV ld

symbcv –g disassociate dev

symld –g remove

symbcv -sid 1234 -g  associate dev BBB 

symrdf -sid 1234 -rdfg 3 -type rdf1 -file rdf.txt -g mydg createpair -establish

May I know if the step is correct and another way to do ? 

Could you please if there is any expert to assist us ?

Thanks, 

Alfred
