Fear of Outdated legacy database systems - Vulnerable Security and un-supported Patches lead several customer who hold their organizations gold mine i.e database to upgrade to the latest versions of their database. In the latest release significant functionality are added for Oracle database 19c from earlier version 12.x.
In a complex, heterogeneous, distributed database environment a coherent upgrade strategy is essential. Truthfully, even organizations with only a single database instance should plan accordingly and approach upgrades cautiously. Failure to plan a Oracle database upgrade can result in improper and inefficient adoption of new features, security, performance degradation of new and existing applications, and downtime.
Worried about disruptions during database upgrades:
- At a minimum, as the DBMS is being upgraded databases will not be available, resulting in downtime and lost business opportunities if the upgrade has to occur during normal business hours (or if there is no planned downtime).
- Possibility of having to convert database file structures
- The possibility that previously supported features were removed from the new release (thereby causing application errors)
- Delays to application implementation timelines and integration breakages
Beyond the above this eBook highlights 4 key pitfalls to avoid ensuring a smooth database upgrade project that moves towards the most cost effective, least disruptive path and to achieve first-time-right solution.
