Scroll to explorePlan an Oracle migration around your workloads
Compare an Oracle upgrade, selective migration and continued operation using your workload, dependencies and support constraints.
Choose a route from your actual Oracle estate
The assessment compares staying on Oracle with upgrading or moving selected workloads. It starts from versions, PL/SQL and application dependencies, workload measurements and recovery requirements. Technical scope and cost assumptions are documented before an implementation is proposed.
Scope an initial Oracle assessment
Inputs, outputs and limits
The first engagement reviews the estate and compares routes with your database and application owners. Its proposed outputs are a workload map, dependency register, route comparison and pilot plan. A production cutover, contractual license determination and guaranteed savings require separate validation and scope.

Inside an Oracle migration plan
An assessment establishes the feasible routes and the evidence needed for acceptance. Upgrade, replication and rollback techniques depend on the source release, target engine and application behavior.
Supported upgrade route
Check the release and patch level, vendor certifications, available support and upgrade prerequisites against current Oracle documentation. Rehearse the selected route and compare query plans and application behavior before production changes. Document the selected support assumptions and the application owners responsible for sign-off.
Technical and licensing inventory
List deployed environments, options, packs, hardware and observed usage. Flag items for review against the organization’s contracts by its licensing specialists. The technical inventory does not establish contractual savings or a legal licensing position. Keep technical observations separate from contractual conclusions and record the remaining questions for specialist review.
Cutover and recovery plan
Assess replication compatibility, write traffic, reconciliation and application changes. Define an acceptable interruption and test the cutover. Once writes reach the target, recovery may require reverse synchronization or restoring data; a connection-string change is not a universal rollback plan. Record who can approve the change and how failures will be escalated.
Migration acceptance tests
Agree schema and data checks, business-function tests, representative workloads, latency and recovery criteria. Test PL/SQL conversions and application semantics. Performance and completeness must be demonstrated on the agreed scope. The pilot produces an evidence record with failures, unresolved dependencies and the criteria for proceeding.
Oracle upgrade, replatforming or exit
An assessment establishes the feasible routes and the evidence needed for acceptance. Upgrade, replication and rollback techniques depend on the source release, target engine and application behavior.

Check the release and patch level, vendor certifications, available support and upgrade prerequisites against current Oracle documentation. Rehearse the selected route and compare query plans and application behavior before production changes.
Selective migration to PostgreSQL
List deployed environments, options, packs, hardware and observed usage. Flag items for review against the organization’s contracts by its licensing specialists. The technical inventory does not establish contractual savings or a legal licensing position.
License perimeter reduction
Assess replication compatibility, write traffic, reconciliation and application changes. Define an acceptable interruption and test the cutover. Once writes reach the target, recovery may require reverse synchronization or restoring data; a connection-string change is not a universal rollback plan.
Oracle migration constraints by sector
Billing cycles, reconciliation obligations and traffic patterns can constrain a database change. The assessment identifies those constraints and the permitted cutover windows for the systems you actually operate.

Questions about Oracle migration
What DBA managers and infrastructure leads ask us before committing to a plan.
What does an initial Oracle assessment require?
Provide database and application inventories, versions and support status, schema and PL/SQL dependencies, representative workload measurements, recovery objectives and permitted maintenance windows. Proposed outputs are a per-workload route comparison, dependency and risk register, effort assumptions, and a pilot and acceptance plan.
Must every workload leave Oracle?
No. Application certification, PL/SQL, operational needs and migration effort may justify remaining on Oracle. A move to PostgreSQL or a managed database must be tested for functional compatibility and total operating cost. The assessment compares the options without assuming one destination is best.
Can the migration avoid all downtime?
That cannot be promised before the estate is assessed. Replication can reduce interruption when source and target support the required behavior. Cutover, write handling, data reconciliation and recovery are tested, with the acceptable maintenance window agreed in advance.
What savings does a license review guarantee?
None before the contracts, usage and target design are reviewed. DNA Solutions can contribute the technical inventory and migration scenarios. Your licensing specialists validate contractual implications. Published company-wide savings do not predict an individual Oracle engagement.
