Telecom Carrier: Extended Maintenance & Phased Migration of Legacy SPARC Systems
Background
A telecom carrier ran its billing and CRM systems on SPARC T7/M7 servers with Solaris 11. After Oracle ended new SPARC system sales in March 2025, OEM support renewal costs kept rising, yet the systems could not be rebuilt overnight, leaving the carrier needing both continuity and an exit path.
Solution
We ran a two-track plan. During the transition, third-party maintenance covered the legacy SPARC estate (parts pool for system boards, CPUs, memory and power supplies, 4-hour response, scheduled inspections). In parallel, migration followed an "edge first, core last" sequence: the billing database was replicated with GoldenGate onto an x86 + Oracle Linux platform, validated side-by-side, then cut over.
Scope of Service
- SPARC parts pool with 4-hour emergency response
- Monthly inspections and firmware health checks for the legacy estate
- x86 + Oracle Linux platform selection and deployment
- GoldenGate dual-track replication, parallel validation and phased cutover
Results
Zero critical downtime during the transition period; the billing database ran in dual-track mode for three months before a window measured in hours; third-party maintenance cost came down noticeably versus OEM renewal, and the proven path now guides further core-system migrations.
