Discovery & Health Check

We audit your current environment, identify risks, deprecated features, invalid objects, and confirm the best upgrade path for your workload and business requirements.

Test Environment Upgrade

We perform a full dry-run in a non-production environment to validate the process, test application compatibility, and identify any issues before the live window.

3
Pre-Upgrade Preparation

Scripts are prepared, backups validated, a rollback plan is confirmed, and all stakeholders are briefed on the upgrade window and contingency procedures.

4
Production Upgrade Execution

The upgrade is executed precisely to plan. We handle every step live, monitoring closely and resolving any unexpected issues in real time.

Databases are verified, statistics gathered, applications tested, and performance benchmarked. You receive a full upgrade report and sign-off confirmation.
