Oracle Sustaining vs Premier Support: What You Actually Get

Premier Support: Full Coverage and Continuous Updates

Oracle Premier Support provides comprehensive support for products throughout their extended support lifecycle. Premier Support includes access to critical security patches, performance fixes, and compatibility updates for new third-party products and operating system versions. Premier Support also includes new feature releases and major version upgrades.

Premier Support costs 22 percent of your licence list price annually and includes dedicated Technical Account Manager support, priority issue resolution, and access to Oracle's advanced support tools. For organisations actively developing, upgrading, and maintaining Oracle products, Premier Support is necessary and appropriate.

Sustaining Support: Minimal Coverage Indefinitely

Sustaining Support is Oracle's minimal tier, available indefinitely after Extended Support ends. Sustaining Support provides critical security patches for publicly known vulnerabilities. However, Sustaining Support does not include new features, performance fixes, or compatibility updates for new third-party products. Sustaining Support includes no version upgrades or new features.

Sustaining Support costs approximately 3 percent of your licence list price annually. For a database licence on Premier Support costing 22 percent, moving to Sustaining Support reduces the cost to approximately 3 percent, an 87 percent cost reduction. For organisations with large Oracle environments, this cost difference is substantial.

The Oracle Lifetime Support Policy and Sustaining Phase

Oracle offers indefinite support for all products through Sustaining Support once Extended Support ends. This means organisations can run Oracle products indefinitely without forced upgrades or licence changes. However, staying on Sustaining Support means accepting your current version forever. No new features, no compatibility updates, and no performance improvements beyond critical security patches.

For mature products where you have no plans to upgrade, Sustaining Support is often the correct choice. If you are running Oracle Database 19c and your roadmap shows Database 23c or later upgrades in the next five to ten years, Premier Support is appropriate. If your roadmap shows no upgrades during this period, Sustaining Support is a viable cost reduction option.

Which Products Are Candidates for Sustaining Support

Sustaining Support is appropriate for products meeting three criteria. First, your organisation must have no plans to upgrade to the latest major releases. If your roadmap includes Database 23c migration or EBS migration to Oracle Cloud ERP, those products need Premier Support. Second, the product must be stable and mature for your environment. New or unstable products require Premier Support's broader support envelope. Third, the product must not be business-critical for innovation or competitive advantage. If Oracle product features directly support your competitive differentiation, Premier Support's access to new features is necessary.

In practice, organisations typically move 30 to 40 percent of their Oracle portfolio to Sustaining Support. Database products used for data warehousing or reporting (where no new version upgrades are planned) are candidates. Older application products approaching end-of-life are candidates. Infrastructure products (Grid Infrastructure, ASM) used for stable, mature deployments are candidates.

Sustaining Support Assessment Framework

For each Oracle product in your environment, answer these four questions. First, is there a planned upgrade to a newer major version within your five-year roadmap? If no, the product is a Sustaining Support candidate. Second, does this product require frequent security patches or vulnerability remediations? If yes, Premier Support's broader security envelope is necessary. Third, does your organisation depend on new features in this product for business differentiation? If yes, Premier Support is appropriate. Fourth, is there significant operational risk or business impact if the product fails? If yes, Premier Support's better support SLAs are necessary.

Products answering no to all four questions are Sustaining Support candidates. Products answering yes to any question should remain on Premier Support. Use this framework to systematically evaluate your portfolio and identify your Sustaining Support opportunities.

Implementation Strategy and Migration Approach

Moving products to Sustaining Support is straightforward administratively. Oracle requires notification of your intention to move products to Sustaining Support, but does not block the transition. However, Sustaining Support migration is typically bundled with broader support renewal discussions. Rather than migrating individual products on an ad-hoc basis, identify your complete Sustaining Support portfolio during your renewal planning (6 to 12 months before renewal), and propose the entire migration as part of your renewal negotiation.

This approach gives you negotiating leverage. By consolidating your support tier changes into a single renewal discussion, Oracle has incentive to support the transition and potentially offer additional discounts for simplifying your support structure. A phased transition is less effective because it creates multiple administrative touchpoints and dilutes your negotiating position.

Document each Sustaining Support migration with your business rationale. This protects you if Oracle questions the migration and provides audit evidence that the decision was deliberate and business-justified, not accidental cost avoidance.

Potential Risks and Risk Mitigation

The primary risk of Sustaining Support is accepting products on versions that eventually become unsupported. Oracle provides extended notice before discontinuing Sustaining Support for major versions, typically five to ten years from initial release. If your Sustaining Support products remain on their current versions indefinitely, this risk never materialises. However, if your business needs force a major version upgrade years later, the effort and cost of this upgrade may be higher because you are jumping multiple versions.

Mitigate this risk by documenting your Sustaining Support products clearly and setting expectations throughout your organisation that these products are on a fixed version with no planned upgrades. This prevents surprise upgrade projects that consume budget and resources. Additionally, maintain regular security scanning for your Sustaining Support products to ensure no critical vulnerabilities remain unpatched. Sustaining Support includes critical vulnerability patches, but these patches must be explicitly requested and installed.

Comprehensive support cost reduction strategy combines Sustaining Support migration with support rate negotiation and third-party alternatives to achieve maximum cost reduction across your Oracle environment.
