ORACLE 12C RAC Modification ocr/votedisk/asm spfile disk group name

Look at me today this single node 12C RAC, suddenly feel that the disk group of OCR is called +dg_sys a little uncomfortable, want to change to +SYS_DG. The approach is to migrate the Ocr/votedisk/asm SPFile to an existing ASM, and then modify the disk group name and finally migrate to the new name Disk group (this process +DG_SYS->+DATA->+SYS_DG)

The disk group where the ocr/votedisk/asm SPFile is modified is complete because the library is a single node RAC, and if the RAC of two or more nodes can be implemented without stopping (restart the node). The process is exactly the same as the 11.2 RAC, There's been no change.
