Legacy File Migration: What LegacyLeaps Fixes
Every scan produces a detailed report. Safe format conversions are automated; VBA remediation is guidance-only in this build.
VBA Compatibility
Updates DAO 3.6 and ADODB 2.5 references to modern versions. Adds missing PtrSafe keywords to Win32 API declarations. Replaces deprecated APIs like FileSearch, Assistant, and CommandBars with working alternatives.
Access Database Migration
Converts .mdb to .accdb format. Updates Jet OLEDB 4.0 provider references to ACE 12.0. Fixes linked tables, form controls, and generates SQL Server migration scripts if you're ready to move off Access entirely.
ActiveX Control Mapping
Maps 24 legacy ActiveX controls to modern replacements. Calendar Controls, PivotTables, Data Access Pages, and other controls that Windows 11 no longer supports are flagged with specific replacement instructions.
Jet SQL Modernization
Detects and converts 18 Jet SQL patterns to T-SQL equivalents. IIf, Nz, DLookup, date literals, string concatenation, and more — all mapped to standards-compliant SQL for SQL Server migration.

Frequently asked questions
Why did my Access database stop working after upgrading to Windows 11?
Windows 11 and 64-bit Office expose incompatibilities in older Access databases, including Jet providers, ActiveX controls, and legacy Data Access Pages. LegacyLeaps reports these risks and provides step-by-step remediation guidance.
Can I migrate my .mdb file to .accdb without losing data?
LegacyLeaps creates a separate output package and keeps the source database untouched. Conversion depends on the installed ACE engine; the report identifies tables, queries, forms, VBA, and provider issues that require validation.
Is my data secure during the migration?
Absolutely. For self-service migrations, your files never leave your computer — everything runs locally. For our done-for-you service, all file transfers use 256-bit TLS encryption, we retain zero data after delivery, and all uploaded files are permanently deleted once your migrated files are returned.
How do I fix broken Excel macros after upgrading to Windows 11?
Windows 11 with 64-bit Office requires PtrSafe declarations on Win32 API calls in VBA. LegacyLeaps converts the file to .xlsm and rewrites the VBA automatically — inserting PtrSafe, updating pointer types to LongPtr, and replacing deprecated APIs — then compiles and validates it. Most files are fixed in under a minute.
What is PtrSafe and why do my macros need it?
PtrSafe is required for Declare statements in 64-bit Microsoft Office. LegacyLeaps adds PtrSafe to your Declare statements automatically during conversion, updates Long pointer types to LongPtr where needed, and replaces deprecated APIs.
Can I bulk convert xls files to xlsx?
LegacyLeaps can scan and convert folders in batches — point it at a folder of .xls files and it converts each one to .xlsx, or .xlsm for macro-enabled files with the VBA rewritten for 64-bit Office. Bulk packs of 10, 25, or 50 tokens are available at volume discounts up to 25% off.
How do I fix VBA compatibility errors in 64-bit Office?
64-bit Office commonly requires PtrSafe, LongPtr, and replacements for deprecated APIs. LegacyLeaps handles all three automatically during conversion, then compiles the rewritten VBA to confirm it builds. Your original file is never modified.
