Im thinking about best way of migrationg and upgrading database from 18.104.22.168 to 12C with reasonable downtime.
reasonable downtime : 30 Minutes
Source : Solaris (Intel)
DB size : 800G
Target : Linux
new DB Name.
Im thinking about using RMAN Duplicate with noopen option ( RMAN Catalog is in use ) . The duplicate will take for sure longer than 30 minutes so just thinking if I can combine duplicate with recovering from archivelogs generated during duplication to minimize the downtime. But is it possible when I'm changing also DB_NAME ?
