Discover the Hidden Legacy Risks in Your Codebase
LegacyScan analyzes your OpenVMS application and identifies all elements that are not directly portable to a Linux platform. It delivers a full breakdown of application compatibility, recommended remediations, and generates actionable development tasks.
Each month, we offer two complimentary high-level LegacyScans, by registration only.
Automated Insight for Legacy Modernization
LegacyScan helps you uncover technical debt and modernization opportunities without disrupting operations.
By analyzing legacy platforms - OpenVMS, Mainframe, and Unix derivatives - we highlight risky interdependencies, missing documentation, and potential migration paths. Whether it’s COBOL, FORTRAN, BASIC, or embedded SQL, LegacyScan delivers immediate value in days, not months.
System Services and API Analysis
LegacyScan detects OpenVMS API calls (e.g., SYS$ENQ, SMG$CREATE_PASTEBOARD) and evaluates the:
- Flags and options supplied to each API
- Compatibility with Sector7's migration toolkit
JIRA is used for issue management and tracking during the scan - to make a database of remediation.
However, we create an Excel database that can be loaded into any tracking system.

We use intelligent analysis to transform undocumented, legacy systems into fully navigable, cross-referenced documentation. With LegacyMap, your COBOL, FORTRAN, BASIC, Pascal, and C++ systems become visual, searchable, and understandable—without rewriting a single line.
Automatically generate documentation from unstructured code—no manual annotations, no guesswork.
Understand how programs, procedures, and modules interact across large, complex systems.
Visualize logic flows and data access in interactive, cross-referenced formats.
For Oracle, Postgres, and Rdb—pulled straight from your embedded SQL.
including multi-language applications.
Whether you’re planning a migration, ramping up new developers, or getting audit-ready, we transform complex, undocumented code into actionable, visual intelligence.

Legacy environments often lack visibility. LegacyScan bridges that gap by automating insight into structure, risks, and dependencies.
A comprehensive PDF and HTML report, including file access charts, call maps, SQL summaries, and system health checks.
Absolutely. Our scan is read-only and non intrusive.
Yes, LegacyScan has multiple phases. Phase 1 is to scan the OpenVMS 3GL or SQL and map the non portable elements against the Sector7 language remediation tools. Sector7 have language remediation tools for all the major OpenVMS languages (C, BASIC, COBOL, FORTRAN, PASCAL, SQL, SQLMOD). If any extensions are detected that are not handled by the Sector7 language remediation tools a JIRA is created for that specific issue and the tool set enhanced.
Yes. LegacyScan detects all use of DCL verbs and syntax. It even follows logicals and symbols through various operations and attempt to reconstruct the values and thus the values passed to the various dcl verbs. LegacyScan will detect all DCL use the is no supported by Sector7's VX/DCL - our 100% compatible implementation of OpenVMS DCL for Linux.
Yes, LegacyScan will detect the use of SMG, FMS and DEC FORMS. All 3 are supported in the Vx/Tools migration toolkit.
Yes, LegacyScan will detect and document the use of all system calls that use the asynchronous capability such and $QIO, $QUI ec Vx/Tools supports IO to devices via the QIO interface with asynchronous even completion (and event flag notification).
Yes, LegacyScan and the Vx/Tools migration tool kit support over 1000 OpenVMS system service calls - SYS$, LIB$, CLI$, SOR$, STR$, SMG$, FDV$, FORMS$ etc .
Yes, LegacyScan and Vx/Tools migration tools kit supporters over 4000 flags to various OpenVMS system services - for example - we support all of the flags to RMS FAB / RAM / NAM / XAB blocks - and we support RMS files. Any flags that LegacyScan find that are not in its database of supported flags is highlighted and placed into an exception report.
LegacyScan will detect 100% of OpenVMS API usage (SYS$, LIB$, STR$ etc) and 99% of the OpenVMS language extensions. LegacyScan understands the capabilities of Sector7's language migration tools. VX/COBOL - Converts OpenVMS COBOL to ANSI COBOL. VX/FPT converts OpenVMS FORTRAN to INTEL ANSI FORTRAN. VX/BASIC compiled OpenVMS BASIC code on Linux. VX/PASCAL converts OpenVMS PASCAL to C++.
