                           OPERATIONAL USER GUIDE
================================================================================

1. PURPOSE & OVERVIEW
--------------------------------------------------------------------------------
This standalone conversion tool updates NAVFIT98A version 33 database files 
(.accdb) to full schema compatibility with NAVFIT98A Version 33 Patch 2. 

It safely creates a copy of your database with all newly required data fields 
while leaving your original database file untouched as a permanent backup.  

NO CODE CHANGES OR INSTALLERS ARE REQUIRED. Does not need admin privileges to run.
This is an Microsoft Access Database file and not an executable.


2. SYSTEM REQUIREMENTS & PREREQUISITES

- Operating System: Windows 10 / 11 (NMCI / Flank Speed / Enterprise Seats)
- Software: Microsoft Access (Access 2016, 2019, or Microsoft 365 Apps)

    NOTE: the new file can be in the same directory as the source file, but DO NOT

          the same file location.
