Legacy System Retirement

Ongoing maintenance of legacy SAP systems after migrating or upgrading to S4/HANA or another modern platform may presents significant operational challenges and associated costs. Retaining complete & active systems solely for historical reporting leads to higher ongoing maintenance fees, software licenses, security vulnerabilities, out-of-date hardware dependencies, and compliance risks. Organizations face the burden of paying full licensing and infrastructure costs just to query historical data occasionally for audits, legal requests, or tax inquiries.

Why Retire Your Legacy System?

Massive Cost Reduction:

Eliminates ongoing maintenance fees, hardware footprint, database licensing, and dedicated IT overhead.

Guaranteed Regulatory & Tax Compliance:

Retains historical records in an audit-ready format compliant with GDPR, HIPAA, and local tax retention mandates.

Reduced Security Risks:

Decommissions unsupported operating systems and databases, avoiding critical security vulnerabilities.

Simplified Data Access:

Consolidates historical data into one secure, searchable archive so business users can query records without logging into multiple legacy systems.

Axcellent Methodology

01

Discovery & Scoping:

Assess your legacy SAP applications, system dependencies, data structures, and statutory retention requirements.

02

Extraction & Archiving:

Extract data, attachments, and metadata securely into an unalterable, Cloud-based, compressed digital archive without information loss.

03

Verification & Audit:

Perform strict reconciliation to ensure 100% data integrity and audit compliance against original SAP records.

04

Decommissioning:

Safely shut down the legacy infrastructure and enable user access via SAP archived retrieval tool or other user friendly interfaces.

Accomplishments / Experience

Business requirements gathering and detailed information analysis of legacy system for extraction more than 2TB of data.

Total 123 ILM objects were created along with the configuration of corresponding audit areas, ILM policies and rules.

Extraction of 31,828 tables with data. No business table with data is left behind.

Record-by-record reconciliation of over 14.6 billion records and justification in case of discrepancy. A detailed spreadsheet has been maintained for reconciliation.

Avoidance of SLT by usage of SAP ILM Snapshot feature for all scoped 123 ILM objects
