Key Takeaway
A legacy EPM migration goes well when it's treated as a chance to redesign planning, not just to copy it. Take stock of what you really use, clean the data and hierarchies first, move in phases, and run old and new side by side until the numbers match.
Many finance teams are still running planning on Hyperion or SAP BPC. In plenty of cases it works. The models are mature, the team knows where everything is, and the close and the budget both get done.
But the cost of staying tends to creep up quietly: support timelines that are getting closer, specialist skills that are harder to hire, customisations nobody wants to touch, and a growing pile of spreadsheets built to do what the system can't.
The hardest part of a migration usually isn't the technology. It's deciding what to bring across, and what to leave behind.
The reasons vary by company, but a few come up again and again: a vendor support horizon that forces a decision, a platform that struggles with modern needs like driver-based planning, scenarios and AI-assisted forecasting, upgrade effort that's rising each cycle, and a shrinking pool of people who know the system well.
Support dates deserve particular attention, because they set a deadline. Third-party summaries of SAP's maintenance schedule currently show the following for BPC. Treat these as a starting point and confirm them against SAP's official documentation for your exact version.
SAP BPC Mainstream Maintenance (to Verify With SAP)
| Version | Mainstream Maintenance Ends | Extended Maintenance |
|---|---|---|
| BPC 10.1 for Microsoft | 30 June 2026 | None mentioned |
| BPC 10.1 for SAP NetWeaver | 31 December 2027 | Offered through 2030 |
| BPC 2021 for SAP BW/4HANA 2021 | 31 December 2027 | Offered through 2030 |

Comparing Your Migration Options
| Path | Best When | Watch Out For |
|---|---|---|
| Move to the vendor's cloud successor | You're happy with the vendor and want the shortest conceptual jump | Cloud versions differ from the on-premise tools, so it's still a rebuild, not a lift-and-shift |
| Re-platform to a modern planning tool | You want a fresh design and better flexibility for finance and operations | Needs a proper requirements and selection process, plus change management |
| Stay put with extended or third-party support | You need time to plan properly or the business is in the middle of other change | It buys time but doesn't modernise, and the underlying problems remain |
| Phased hybrid | Some processes are ready to move and others are not | Running two systems adds complexity, so it needs a firm end date |
Take Stock Before You Decide Anything
List every model, rule, report, form, integration and user. Note what's actually used, by whom and how often. In most legacy environments a surprising share of what exists isn't needed anymore, and every item you retire is one you don't have to rebuild.
Redesign, Don't Replicate
A migration that copies the old build moves the old workarounds with it. Start from how planning should work today, then decide how the new platform supports it. Treat each legacy customisation as a question, not a requirement.
Clean the Data and Hierarchies First
Inconsistent hierarchies, duplicate accounts and unclear metadata become much more expensive to fix after go-live. Agree definitions and ownership now, and load the new platform with data you trust.
Choose the Platform on Requirements
Define what finance and the business need, including scenarios, integration, scale and who will maintain it, then evaluate options against those needs. Picking the tool before the requirements usually means adapting the process to fit it.
Phase by Process and Run in Parallel
Move one process at a time, such as the forecast or workforce planning, rather than everything at once. Run old and new together for at least one cycle and reconcile the results, so finance can trust the new numbers before the old system is switched off.
Invest in People, Not Just the Build
Train users early, name super-users in each team, and set clear ownership of the new models. A technically perfect migration still fails if the people who rely on it don't trust or understand it.
Plan the Exit From the Old System
Decide what history needs to be archived, what audit evidence must be kept, and when the legacy system is formally retired. Without an end date, the old system tends to live on alongside the new one indefinitely.
A migration that only copies the old system moves the old problems too. The best ones leave finance with a better process, not just a newer tool.
Confirm your support dates, then run a short assessment of what you have today: how it's used, where the workarounds are and what the business needs next. That gives you the facts to choose between the paths above, and a realistic scope, timeline and budget.
Keansa helps finance teams plan and carry out EPM migrations: assessing the current environment, defining requirements, selecting and implementing the right platform, and moving in phases with parallel runs, so the new system is trusted from day one.
