A global industrial manufacturer faced a $1.4M on-premise Solaris/SPARC hardware refresh while finance teams waited 11 hours every month-end for Oracle ERP batch jobs to finish. SNWN migrated their 14-terabyte Oracle E-Business Suite, WMS interfaces, and reporting databases to Oracle Cloud Infrastructure (OCI) Base Database and Exadata Cloud Services using Oracle Data Guard. Cutover completed in 8 minutes with zero delayed factory shipments, batch runtimes sped up 3.1x, and 5-year licensing and hardware costs fell by 36%.
Aging On-Premise Hardware and 11-Hour Month-End Close Bottlenecks
Every manufacturing plant across Europe, North America, and Asia relied on one central Oracle ERP instance to print shipping manifests, post bill-of-materials updates, and invoice distributors. Because factories ran 24 hours a day across overlapping time zones, taking the ERP offline for a full weekend migration was out of the question.
Key Operational Bottlenecks Before the Project
- End-of-life server maintenance renewals and storage expansion quotes exceeded $1.4M upfront.
- Month-end costing and general-ledger consolidation jobs ran 11 hours straight, locking out regional controllers.
- Any ERP outage longer than 20 minutes halted warehouse barcode label printing and truck dispatch.
How We Executed an 8-Minute Global ERP Cutover to OCI
We rehearsed the entire switchover three times in production-sized clones before touching live factory traffic.
Right-Sized OCPU Licensing and Mapped All 48 Plant Integrations
Before provisioning a single cloud node, we audited CPU peak curves and Bring-Your-Own-License (BYOL) entitlements on OCI, saving 28% on Oracle processor licensing right from the architecture blueprint.
Built Dual-Region OCI Landing Zones with FastConnect Private Links
Using OCI Resource Manager (Terraform), we deployed primary compute and high-IOPS database tiers in Frankfurt with Cross-Region Data Guard standby in Amsterdam, linked privately to plant MPLS routers.
Synced 14 TB Continuously via Oracle Data Guard and GoldenGate
We seeded encrypted initial backups over private fiber and kept cloud standby databases continuously in sync via redo transport while running three full-load performance dress rehearsals with finance users.
Switched Production Role in 8 Minutes and Tuned Top SQL Bottlenecks
During a quiet Sunday shift change, we paused application queues, executed a clean Data Guard role switchover in under 8 minutes, verified Zebra warehouse label printing across 9 countries, and tuned slow batch SQL queries.
Faster Financial Close and Predictable 5-Year Cloud Economics
Controllers now close monthly books in a single afternoon instead of pulling overnight shifts, and zero trucks were delayed during the cloud switchover.
Faster ERP Batch Processing
Month-end consolidation dropped from 11 hours to 3.5 hours on OCI NVMe storage.
Actual Global Cutover Window
Zero lost transactions and zero delayed factory shipments across 9 countries.
5-Year TCO Savings
Avoided $1.4M hardware capex and optimized BYOL OCPU autoscaling.
Day-to-Day Business Impact
- Automated cross-region disaster recovery tests now finish in 12 minutes instead of a full weekend.
- BI reporting queries moved to a read-only Active Data Guard replica so heavy reports never slow down warehouse scanners.
- Backed by SNWN's 24/7 Oracle DBA and Linux infrastructure operations team.
Tools, Platforms, and Technologies Used
Every component in this deployment was selected for long-term stability, clear observability, and straightforward handover so internal engineers never get locked into black-box scripts.

Frequently Asked Questions About This Project
Why choose Oracle Cloud (OCI) instead of AWS or Azure for heavy Oracle ERP databases?
OCI supports flexible OCPU scaling, Bring-Your-Own-License (BYOL) favorable core factors, native RAC/Exadata services, and low outbound bandwidth pricing - often costing 30% to 45% less for heavy Oracle database workloads.
How did you migrate 14 terabytes over the network with only 8 minutes of downtime?
The 14 TB bulk transfer happened weeks ahead in the background while factories worked normally. Oracle Data Guard shipped tiny incremental redo logs continuously, so cutover day only needed a brief 8-minute role flip.
Does SNWN provide ongoing 24/7 Oracle DBA management after migration?
Yes. Our certified DBAs and OCI cloud engineers handle 24/7 performance tuning, quarterly PSU security patching, clone refreshes for developers, and disaster-recovery testing.
