Question about going back to Shared SPFILE from Local SPFILE in RAC

We have a two node RAC Database where each node is using a separate, local SPFILE.  I 'think' this is due to a mistake where someone created a PFILE from SPFILE and then SPFILE from PFILE without specifying the shared location.  I need to change it back to both nodes using a shared SPFILE as recomended.  We are not using ASM.

Is this the correct procedure?

1.  Create PFILE from SPFILE

2.  On node 1, create SPFILE from PFILE to shared location:  create spfile='O:\oradata\dbname\spfileCLUSTER.ora' from pfile='O:\oradata\dbname\PFILE_NODE.ora'

2.  On node 2, create SPFILE from PFILE to shared location: create spfile='O:\oradata\dbname\spfileCLUSTER.ora' from pfile='O:\oradata\dbname\PFILE_NODE.ora'
