The path to Oracle Solaris Cluster Geographic Edition software to upgrade from an Oracle Solaris Cluster 3.3 5/11 and Oracle Solaris 10 cluster to a platform based on Oracle Solaris Cluster 4.0 and Oracle Solaris 11 with minimum downtime is outlined in a post by Tim Read, who has prepared an eight-part map to the process. The heart of Read's method is to use Oracle Solaris Cluster Geographic Edition software to overcome the latency involved in using Oracle Solaris Cluster, which develops during cold-failover operations where the database is briefly unavailable. Oracle Solaris Cluster Geographic Edition enables manual initiation of an automated sequence of steps that control application start and stop commands and the direction of data replication, Read explains. It allows you to cut over to the new cluster while still having the option to back out in case anything goes wrong. Implementing such a configuration enables a safer upgrade, and it also provides a potential platform for disaster recovery.
