Hi, it's possible to upgrade Oracle Clusterware 10g R2 (10.2.0.5) to a standard configuration GI 12
Upgrade guide states: "To upgrade existing Oracle Clusterware installations to a standard configuration Oracle Grid Infrastructure 12c cluster,
your release must be greater than or equal to Oracle Clusterware 10g Release 1 (10.1.0.5), Oracle Clusterware 10g Release 2 (10.2.0.3), Oracle Grid Infrastructure 11g Release 1 (11.1.0.6), or Oracle Grid Infrastructure 11g Release 2 (11.2)."
I'm in 10.2.0.5, is the direct upgrade to 12c clusterware posible or I need to do a previous step to 11g clusterware?
