Hyperion Planning, HFM and Essbase have served Riyadh groups for years, but Oracle's investment has moved to EPM Cloud, and support for on-premise versions is limited. The timeline often forces the migration decision, so the part you control is doing it deliberately.

Rules written by people who have since left the business are the main risk. They need to be audited and understood before anything is moved, because copying them across unexamined carries the old platform's workarounds into the new one.

Auditing what you have

The first phase is an inventory: which applications are live, which business rules still execute, which reports are used versus generated and ignored, and which calculations depend on member structures that no longer reflect the business. Many Hyperion estates carry unused forms and superseded rules, and migrating them carries cost and complexity forward for no reason.

Rebuild versus replicate

Straight replication is tempting because it feels lower risk, but it imports every historical workaround into a platform that may not need them. We assess each significant rule and decide with you whether it is a business requirement worth rebuilding or an artifact of the old platform that should be retired. Whether EPM Cloud's consolidation functions replace a given custom rule is confirmed rule by rule.

Data and history

How much history to migrate is a decision with a cost attached. A common approach is to move several years of actuals plus the current budget and forecast cycles, and archive the rest in an accessible format. Reconciliation is run at every level, by entity, account and period, so the first close on EPM Cloud can be tied to the last close on Hyperion.

A hypothetical example

Imagine a Riyadh holding company that runs HFM for consolidation, with Essbase calculations written by a consultant who has since left. Nobody on the finance team can explain two of the elimination rules. An audit during migration could trace them to an ownership structure that later changed, which would show why rebuilding a rule can be safer than replicating it.

Parallel running and cutover

The new EPM application runs alongside Hyperion for a full close and a budget cycle, with variances investigated and explained rather than accepted. Cutover happens only when both produce the same numbers and the finance team can operate the new platform without the old one as a safety net. This links to consolidation process design.

Rethinking the close calendar while you migrate

A migration is a moment when a finance team will accept changes to a close process it has run the same way for years. It is a chance to review which reconciliations still earn their place, which approval steps add control and which only add delay. This connects to broader process improvement and to reporting design, because moving an inefficient process onto a better platform preserves the inefficiency at a higher licence cost.
