Review this information to convert to an Oracle Extended Cluster after upgrading Oracle Grid Infrastructure. Oracle Extended Cluster enables you to deploy Oracle RAC databases on a cluster, in which some of the nodes are located in different sites.

1. As root user, log in to the first node, and run the command:

   rootcrs.sh -converttoextended -first -sites list_of_sites -site node_site

   list_of_sites is the comma-separated list of sites in the extended cluster, and node_site is the node containing the site.

   For example:

   rootcrs.sh -converttoextended -first -sites newyork,newjersey,conn -site newyork

2. As root user, on all other nodes, run the following command:

   rootcrs.sh -converttoextended -site node_site

   node_site is the node containing the site.

   For example:

   rootcrs.sh -converttoextended -site newjersey
   

3. Delete the default site after the associated nodes and storage are migrated.

   crsctl delete cluster site site_name

   For example:

   [root@node4]#crsctl delete cluster site mycluster
