R12.2 Move concurrent processing node.

Do you have a reference for moving a concurrent manager node in R12.2?

We want to move the CM node from HRT-ERPTSTCM-01  to   HRT-ERPTST-01

I found Concurrent Processing - How To Move Concurrent Processing Server from One Node To Another Node (Doc ID 373611.1) but it is for 11.5.10.2

We are already on a 3 node shared APPL_TOP, when you grep from HRT-ERPTST-01 and HRT-ERPTSTCM-01 you see the same settings.

grep s_isConc $CONTEXT_FILE

         <TIER_NODE oa_var="s_isConc">YES</TIER_NODE>

         <TIER_NODEDEV oa_var="s_isConcDev">YES</TIER_NODEDEV>

grep s_concstatus $CONTEXT_FILE

            <oa_service_status oa_var="s_concstatus">enabled</oa_service_status>
