Migrating Oracle databases can be a tall order. The process is often complex and can be costly. Sometimes, however, migration is unavoidable. This is especially true when support and licensing considerations come together to make migration a necessity. And when migrating business-critical databases, it is important to provide high availability protection to prevent downtime, which results in lost revenue and productivity. Oracle has announced that support for Oracle Database 12c will soon end. Therefore, organizations running Oracle Database 12c will face the imminent requirement to migrate.
