Hyperion Migration
Legacy Hyperion environments are expensive to maintain and increasingly hard to staff. We migrate metadata, business rules, historical data, and reporting from Hyperion Planning and HFM into OneStream, validated against your existing results before cutover.
Capabilities
What This Engagement Covers
- Metadata and hierarchy migration from Hyperion Planning and HFM
- Business rule and calculation logic re-platforming
- Historical data migration with tie-out validation
- Parallel run support against legacy results
- Change management for finance teams moving off Hyperion
Our Process
How We Deliver It
01
Legacy Assessment
We inventory your existing Hyperion build — metadata, rules, and integrations — before scoping the migration.
02
Re-platform
Metadata and logic are rebuilt natively in OneStream, not just lifted and shifted.
03
Parallel Validation
Results run side-by-side with legacy Hyperion until numbers tie out with confidence.
04
Cutover & Decommission
We support the final cutover and help retire the legacy environment cleanly.
