Imagine facing a hard deadline to shut down a costly data center, only to discover your most critical 100TB of encrypted data is completely inaccessible. Lost encryption keys made cloud migration impossible… or so everyone thought.
PROBLEM: Encryption Deadlock + Infrastructure Chaos
A global automotive leader needed to decommission one of two primary data centers due to skyrocketing costs. Their fragmented environment, IBM AIX (Oracle 10g), Oracle Database Appliance, and Exadata was already complex. But the real crisis? Over 100TB of TDE-encrypted data with lost master wallet passwords for years, blocking non-CDB to PDB conversion and cloud migration entirely.
AGITATION: The Stakes Couldn’t Be Higher
- Financial hemorrhage: Dual data center costs spiraling out of control
- Security nightmare: Operating with lost encryption credentials (compliance disaster)
- Migration impossibility: Oracle couldn’t solve it; industry standards failed
- Deadline pressure: Decommissioning timeline ticking while competitors modernized
- Leadership exposure: Millions in wasted spend if they missed the deadline
SOLUTION: Croyant’s Innovation Blueprint
- Cracked the Encryption Code: Used autologin + strategic wallet-merging to bypass lost passwords, successfully converting 100TB across multiple databases to Oracle 19c Multitenant where Oracle failed.
- Smart Data Movement: Deployed Azure Data Box for physical RMAN backup transport, avoiding massive ExpressRoute bandwidth costs.
- Hybrid Resilience: Built Active Data Guard + Data Guard Broker for real-time sync between on-premise DCs and Oracle Exadata Cloud@Azure (ExaDB-C@A).
- Production Proof: Ran full production switchover for 1 week on cloud—live data, live loads—before permanent transition.
OUTCOME: 30-40% Cost Slash + Modernized Future
- Massive savings: 30–40% operational cost reduction via data center decommissioning + Exadata elastic scaling
- Security restored: From “lost password risk” to fully managed, compliant TDE architecture
- Modern architecture: Legacy silos → containerized Oracle Multitenant with automated backups + cloud monitoring
The Client’s Words
“You faced some significant technical challenges converting the databases to PDBs, which I understand Oracle couldn’t resolve. That’s pretty special! It was wonderful to see such a fantastic team effort. Of course, the planning was really very good, too. It’s not easy coordinating all the different teams!”

This wasn’t migration. This was infrastructure resurrection, turning an impossible problem into a competitive advantage.
