After the Go-Live: Optimizing Your SAP Licenses Post-Migration
Introduction: Why Post-Migration SAP License Optimization Matters
Migrating from SAP ECC to S/4HANA is a huge milestone, but going live is not the end of the journey. Without careful post-migration license optimization, organizations risk overspending on SAP licenses.
Once S/4HANA is live, SAP will be keen to maximize its revenue – meaning any unused licenses or misclassified users could translate into unnecessary costs for you.
An immediate SAP license reconciliation after upgrade often reveals surprises. Many companies find they have S/4HANA licenses for users who no longer need them or are assigned to overly expensive license types. Read our overview of SAP S/4HANA Migration Contracts & Negotiation.
This hidden shelfware or misclassified usage can quietly drain your IT budget if left unchecked. SAP S/4HANA license audits and true-ups after go-live will expose these inefficiencies – so it’s better to catch and correct them yourself first.
Proactive optimization now also strengthens your hand in future contract talks. By cleaning up license allocations and usage early, you avoid carrying waste into your next renewal.
A lean, right-sized license profile puts you in a stronger position to negotiate with SAP. In short, optimizing post-migration licensing protects your budget and ensures SAP license compliance after go-live on your terms.
Step 1 – Conduct an Immediate S/4HANA License True-Up
As soon as S/4HANA is live, perform an internal license true-up. Don’t wait for SAP to insist on it – do it yourself within the first few months post-migration.
This means reconciling what you purchased versus what’s actually in use. Check your S/4HANA user lists, engines, and FUE counts against your entitlements.
Identify any gaps or overages early. If some active users weren’t included in your initial license count, address it now to avoid compliance issues later.
More commonly, you’ll find you’re over-licensed. Discovering duplicate accounts or unused licenses is a chance to reassign or retire them before they become a cost liability.
An immediate true-up also provides hard data for adjustments. For example, if you budgeted for 1,000 users but only 800 are active, you have 200 licenses of headroom.
While SAP may not refund those outright, you can leverage that surplus: negotiate applying it to other needs or use it as a credit in future discussions, rather than letting it go to waste.

Step 2 – SAP User Reclassification and FUE Reconciliation
After migrating, make sure each user is on the right license type. In ECC, you had named-user categories (Professional, Limited, Self-Service, etc.).
Now, in S/4HANA, especially under a RISE subscription, users are counted in Full User Equivalents (FUEs) or new categories. The mapping isn’t one-to-one, so it’s easy to misassign licenses during the transition.
Scrutinize how your ECC users were translated to S/4HANA licenses. Don’t let everyone inherit a costly “Professional” license by default.
Many users who just run reports or do simple tasks might qualify for a lower-tier license. By reclassifying those users to the proper tier (or a smaller FUE weight), you can slash costs significantly.
Negotiate flexibility with SAP for this true-up. If you discover dozens of users who can be downgraded, ask SAP to allow a post-migration adjustment with minimal fuss.
The goal is to avoid paying for “Cadillac” licenses when a “sedan” license would do. Adjusting license assignments in the months right after go-live ensures you’re not locked into an inflated license count.
Step 3 – Address Shelfware and Unused SAP Licenses
After go-live, many companies discover a chunk of their SAP licenses are now “shelfware” – paid for but sitting unused. In fact, it’s not uncommon to see 10–20% of licenses idle post-migration.
These could be user accounts for employees who left during the project or entire modules that were never implemented in S/4HANA. Every unused license is wasted spend if not addressed.
To tackle shelfware, first identify it. Use your S/4HANA usage reports to flag any user who hasn’t logged in since go-live and any modules or components that aren’t being used.
Then take action: reclaim those user licenses into a pool for future needs, or remove their access so they don’t count against your totals. For unused modules, talk to SAP about dropping them from your contract or at least suspending maintenance on them.
Also, be wary of automatic renewals or true-ups. If you moved to S/4HANA on subscription, SAP might automatically renew whatever count you initially bought – including unused pieces.
Proactively cancel or reduce any shelfware licenses before renewal time. The aim is simple: eliminate or reallocate what you’re not using, so you’re not paying a “shelfware tax” through the next few years.
Step 4 – Managing S/4HANA Subscription Costs and Growth
Going live with S/4HANA is just the beginning – usage often grows as more users and data come on board. Keeping your S/4HANA subscription costs under control is critical to avoid surprises.
If you’re on RISE with SAP or another S/4HANA cloud subscription, you have a contracted user count (in FUEs) or usage volume. Now that you’re live, put tools and processes in place to track your consumption against those contract limits.
Continuously monitor your FUE consumption versus what you’ve licensed. SAP provides admin dashboards or reports on user counts and other metrics. Use these to spot trends.
For example, if more departments start using S/4HANA or transaction volumes spike, you’ll see usage creeping toward your limits. Catching that early lets you manage it – either by curbing unnecessary use or budgeting for a true-up.
Also, negotiate flexibility for growth. Ensure your contract has some buffer or “burst” capacity (say an extra 5–10% of users or transactions) before triggering a big cost increase. You don’t want a temporary peak (like a seasonal surge or a one-time project) to lock you into higher fees permanently.
Work with SAP on a framework for handling overages – for example, an annual reconciliation at fixed rates or a short-term expansion clause. With the right terms, you can accommodate growth without letting costs spiral out of control.
Step 5 – True-Down and SAP License Optimization Strategy
Most SAP agreements make it easy to add licenses but difficult to relinquish them. To avoid overspending, you need a plan to true-down as well as true-up. In the post-migration period, identify any licenses you truly don’t need and prepare to remove that fat from your contract.
Start by quantifying the excess: if a chunk of your S/4HANA users are idle or redundant, that’s leverage.
Approach SAP to discuss options for reducing those licenses. In some cases, you might negotiate a true-down clause – for instance, the ability to drop a chunk of licenses after year 2 of a 3-year deal if your usage falls. SAP won’t offer this readily, but if your business headcount shrinks or you divest a division, it’s worth requesting flexibility.
Even if SAP refuses any mid-term reductions, make sure you’re ready to optimize at renewal. Document all the shelfware and low-use licenses you’ve identified, and let SAP know you intend to cut that out of the next contract.
By signaling early that you will not renew unnecessary licenses, you set the stage for a leaner, more cost-effective deal. This proactive approach forms the core of your SAP license optimization strategy going forward – only paying for what you actually use.
Step 6 – Continuous SAP License Optimization Post-Go-Live
Optimizing your SAP licensing is not a one-and-done task – it requires ongoing effort. Establish a practice of continuous license management now that S/4HANA is live to keep usage efficient and compliant.
Schedule regular internal license audits (for example, quarterly or bi-annual). Use SAP’s tools or third-party Software Asset Management (SAM) solutions to monitor user activity and license consumption.
These internal audits will spot dormant accounts (e.g., users who left the company) or misclassified users before they become a problem. You can then quickly free up those licenses or adjust their type.
In addition, implement clear governance for SAP licenses. Coordinate with HR so that whenever an employee leaves or changes roles, their SAP access is updated or removed immediately – preventing licenses from lingering unused.
By enforcing these practices, you’ll continuously reduce post-migration shelfware and make sure you’re only licensing what your business actually needs.
Post-Migration License Issues and Optimization Actions
| Post-Migration Licensing Issue | Risk / Cost Impact | Optimization Action |
|---|---|---|
| Over-purchased FUE licenses | Paying for unused user capacity; wasted budget on shelfware | Reclassify or reduce user counts; negotiate a true-down at renewal |
| Dual-use overlap with ECC | Double-paying (maintenance on ECC + subscription for S/4); redundant costs during transition | Negotiate dual-use rights or a maintenance holiday to avoid overlap costs |
| Shelfware after go-live | 10–20% of licenses idle post-migration; ongoing fees with no value | Reclaim & reassign unused licenses; terminate or remove idle modules before next true-up |
| Uncontrolled subscription growth | Cost overruns from FUE increases or extra usage; budget uncertainty | Monitor usage closely; set contract caps or alerts; negotiate flex rights for growth spikes |
| Digital access miscounting | Unexpected SAP audit exposure and back-charges for indirect use | Audit digital access documents early; clarify SAP digital access true-up rules in contract |

FAQ: SAP S/4HANA Post-Migration Licensing
Q1: When should we do our first S/4HANA license true-up?
A1: Within 90 days of go-live. This early true-up catches any over-licensing or shortfalls while you can still correct course easily.
Q2: Do we still need ECC licenses after migrating to RISE?
A2: No – once on RISE, ECC licenses can be retired. However, negotiate dual-use rights during the transition so you’re not paying double during any overlap period.
Q3: How can we reduce post-migration shelfware?
A3: Reclaim unused licenses regularly and keep a license pool for new needs. Also, maintain governance to prevent buying more licenses when you already have unused ones.
Q4: What is FUE reconciliation in S/4HANA?
A4: It’s mapping legacy named users to Full User Equivalents under S/4HANA’s model. In short, you translate old user licenses into FUE values and ensure the total aligns with actual usage.
Q5: Can we lower license counts after go-live if we overestimated?
A5: Only if you negotiated that ability up front. Most SAP agreements won’t let you reduce licenses mid-term, so you’d trim the excess at renewal time unless a true-down was agreed.
Q6: How do we track subscription growth in RISE with SAP?
A6: Monitor user counts and usage with cloud or SAP tools. Set up alerts as you approach limits so you can adjust or expand in time.
Q7: What’s the best way to prepare for the next SAP renewal?
A7: Build a data-driven SAP license optimization strategy well before renewal. Track actual usage and eliminate shelfware. With these insights, you can negotiate your next SAP contract from a position of strength.
