Sybase ASE to SQL Server — Modernise via S2SIM

Exit Sybase ASE while staying on the Microsoft stack — S2SIM automates compatibility mapping, schema modernisation, stored procedure conversion, and SQL Server Agent job modernisation so your team focuses on validation, not manual rewriting.

What We Cover

Six pillars of a complete S2SIM modernisation

From the first compatibility scan through to post-go-live validation — every phase handled by specialists who know both ASE and SQL Server deeply.

Compatibility Analysis

S2SIM maps Sybase ASE T-SQL to SQL Server T-SQL, flagging dialect differences, deprecated features, and datatype mismatches before a single object is converted.

S2SIM Automated Conversion

The AI agent converts schema, DDL, and stored procedure signatures automatically — maximising automation before expert review, so your engineers spend time on decisions, not rewrites.

Stored Procedure Modernisation

T-SQL procedures adapted from ASE dialect to SQL Server — cursor handling, error handling, and SET options reconciled with precision by engineers who know both dialects.

SQL Server Agent Job Modernisation

Sybase ASE scheduler jobs converted to SQL Server Agent jobs with schedule and step parity — no manual recreation of job definitions or execution logic.

Parallel Bulk Data Transfer

High-throughput data transfer with row-count and checksum reconciliation at table level. Transfer runs in parallel to minimise the modernisation window and eliminate guesswork at cutover.

Post-Modernisation Validation

Execution plan review, statistics update, and full application smoke test on SQL Server before go-live. Issues caught in staging, never in production.

Why Modernise?

From Sybase ASE to SQL Server — staying in the Microsoft ecosystem

If your organisation runs on Windows Server, Azure, or Microsoft tooling, SQL Server is the natural landing zone from ASE. S2SIM keeps you in a familiar ecosystem while eliminating the SAP dependency and the shrinking talent pool.

Stay in the Microsoft stack
SQL Server shares T-SQL syntax with ASE — the dialect gap is narrower than any other target. Teams already familiar with SSMS, SQL Server Agent, and Windows authentication have a shorter learning curve than any alternative.
Escape end-of-life risk
Most ASE deployments run on versions that received their last security patch years ago. SQL Server 2019 and 2022 are actively patched — removing the compliance and security exposure of staying on unsupported ASE.
Azure-native integration
SQL Server on Azure SQL Managed Instance or Azure SQL Database integrates natively with Entra ID, Azure Monitor, and the full Azure data platform — something ASE was never designed to do.
Larger, growing talent pool
SQL Server DBAs and developers are abundant. ASE expertise is retiring. Modernising now means your next DBA hire is a standard SQL Server search — not a specialist recruitment exercise.
Consolidated licensing
Organisations already paying for SQL Server licences through EAs or CSP agreements often find that consolidating ASE workloads onto SQL Server reduces net database spend — removing a second licence relationship entirely.
Modern HA and DR features
Always On Availability Groups, automatic failover, and readable secondaries give SQL Server HA capabilities that require significant ASE Replication Server complexity to approximate — at a fraction of the operational overhead.
How S2SIM Works

The S2SIM pipeline, from scan to SQL Server

Compatibility scan before any conversion starts. S2SIM catalogues every stored procedure, scheduler job, and T-SQL pattern in the ASE source — producing a structured report that scopes work and flags risks before a single object is touched.

AI agent automates schema and dialect conversion. Datatype mappings, reserved word collisions, implicit conversions, and SET option semantics resolved in a single automated pass — covering the bulk of what would otherwise be manual re-coding.

Specialists close the remaining gaps. Cursor behaviours, @@rowcount semantics, quoted identifier handling, and other ASE-specific patterns that need contextual judgement — S2SIM surfaces these, our engineers resolve them.

Our Process

Four steps from ASE to SQL Server

A structured engagement with clear hand-off points — no surprises mid-modernisation.

ASE Discovery & S2SIM Scan

S2SIM agent scans all schema objects, stored procedures, scheduler jobs, and data volume. Compatibility report produced before work begins — you see the full scope before committing.

S2SIM Automated Conversion

AI pipeline converts schema and stored procedures. Output reviewed by a Sybase and SQL Server specialist before proceeding to staging — automation maximised, quality assured.

Expert Gap Resolution & Testing

Engineers resolve remaining dialect differences. SQL Server Agent jobs created. Full regression run in staging against your application — sign-off before any cutover date is set.

Cutover & Post-Modernisation Support

Parallel data transfer and lightweight application re-point. 30-day post-modernisation support included — named engineers available if anything surfaces after go-live.

Tech & Tools
