Oracle ACE and Performance Tuning Corporation (PTC) founder, Ed Whalen discussed data migrations or upgrades, the choices ahead for your organization and how they relate to 12c. For more information about this topic, visit Performance Tuning Corporation website at www.perftuning.com . The currently released version of Oracle Database 12c is the one most organizations will begin to migrate to this year and yet few organizations have the experience necessary to understand the issues that must be addressed to avoid pitfalls such as downtime, delays, or over-spending. Oracle ACE Ed Whalen, a 20+ year industry veteran, Performance Tuning Corporation founder and distinguished author will provide advanced best practices for upgrading or migrating Oracle databases. Depending on specific system configurations, requirements and business needs, there are numerous methods for performing this vital activity and choosing the right one is critical. This webinar abswers questions such as: - When to upgrade or migrate an Oracle database? - What are the options for migration or upgrade? - What is the best method? Performance Tuning's Lunch & Learn is focused on management, planning, and budgeting, not features and technology, and will provide you and your management teams the information they need to perform the next database upgrade or migration cycle.
