Upgrade Assessment
We analyse your current system version, installed components, custom code volume, integration landscape, and business dependencies to define the upgrade path, effort estimate, and risk profile.

SAP S/4HANA Upgrade Services Stay Current. Stay Competitive.
SAP releases a new version of S/4HANA annually. Staying current isn’t just a technical obligation — it’s the fastest route to new AI capabilities, security improvements, and process innovations. Aevitas IT makes version upgrades structured, predictable, and low-risk.
- The Case for Staying Current
Why SAP Upgrades Matter More Than Ever
SAP supports each S/4HANA release for five years from the date of general availability. As releases age, access to new features — including SAP’s rapidly evolving Business AI capabilities through Joule — is limited. Organisations on older releases risk falling behind competitors who are already leveraging AI-driven automation in finance, supply chain, and procurement.
Aevitas IT manages the full upgrade lifecycle: from initial technical assessment and custom code impact analysis through system conversion, testing, and go-live. We work in both on-premise and private cloud environments, and support customers navigating the path to SAP Cloud ERP (the public cloud edition of S/4HANA).

SAP S/4HANA Annual Release Cadence
- Legacy releases — limited or no access to new AI features
- Supported — current Joule & Business AI capabilities
- Latest — full AI, automation & innovation access
SAP releases a new version of S/4HANA each year. Each release carries a five-year mainstream maintenance window. Staying current is the most direct route to SAP Business AI and Joule capabilities.
- Our Approach
A Risk-Managed Upgrade Process
2
Custom Code & Clean Core Analysis
Using SAP's custom code analysis tools, we identify which developments are affected by the upgrade, which can be retired, and which need remediation — reducing the upgrade scope and long-term maintenance burden.
3
System Conversion & Configuration
Technical conversion is executed in a sandbox environment first, followed by development and quality assurance systems. New features and changed processes are configured and validated before production upgrade.
4
Regression Testing
Comprehensive regression testing — combining manual business process testing with automated test tools — validates that all existing functionality continues to operate correctly in the upgraded system.
5
Production Upgrade & Hypercare
A well-rehearsed cutover plan is executed over a planned downtime window, with rollback procedures prepared. Hypercare support follows the go-live to resolve any post-upgrade issues rapidly.

Frequently Asked Questions
How disruptive is an S/4HANA upgrade to daily operations?
With proper cutover planning, disruption is limited to a planned downtime window, not an extended period. Our approach — sandbox conversion first, then DEV and QA, followed by rehearsed cutover with rollback procedures ready — is designed specifically to protect business continuity for organisations that cannot tolerate extended outages.
What happens to our custom code during an upgrade?
Custom code is assessed early, in the Custom Code & Clean Core Analysis step, using SAP's analysis tools to identify what's affected, what can be retired, and what needs remediation. This reduces upgrade scope and is often the moment organisations meaningfully reduce their long-term maintenance burden, see the Custom Code Remediation page for more detail.
Do we have to upgrade every year to stay supported?
No, each S/4HANA release carries a five-year mainstream maintenance window, so you have flexibility in timing. That said, staying closer to the current release gives earlier access to Joule and Business AI capabilities, which is a factor worth weighing alongside pure support-deadline pressure.
