What you get with this Offer
I will plan and execute an Oracle Database version upgrade — from your current version (11g, 12c, 18c, or 19c) to a target version — covering pre-upgrade compatibility assessment, deprecated feature identification and remediation, upgrade execution using DBUA or command-line methodology, post-upgrade validation, and a rollback plan for critical issues discovered during upgrade. Oracle Database upgrades that are executed without pre-upgrade assessment and a tested rollback plan frequently encounter preventable compatibility failures — deprecated initialisation parameters, invalid objects from changed PL/SQL behaviour, and application connectivity changes — that extend the outage window far beyond the planned downtime.
The engagement covers pre-upgrade compatibility check with Pre-Upgrade Information Tool, deprecated parameter and feature remediation, invalid object compilation baseline, upgrade execution in a test environment first, post-upgrade invalid object recompilation, regression testing against critical PL/SQL packages, and a fallback procedure document for restoring the previous version.
Designed for Oracle database teams planning or preparing for a version upgrade who need the upgrade managed by an experienced Oracle DBA with a systematic, risk-managed approach.
