multi node refresh

Hi Support,

We are on R12.2.5 with 2 node application and 2 node rac database.

We have a clone from prod to existing uat(2node to 2node).we use shared application tier in both source and target.we have unzipped the EBSapps folder in target primary node and ran adcfgclone with existing backup xml file and it went successfully

Now,what steps needs to be executed in secondary node in target

1)do we need to run adcfgclone again on secondary node with backup xml file

OR

2)Just run autoconfig with backup xml file

OR

3)perl ./adclonectx.pl addnode contextfile=backup_xml_2ndnode dualfs=yes
