TongPin upgrade preparation

1. Identify the original working folder and version.
2. Back up the complete folder and protect your account/licensing data.
3. Exit the old program before replacing the files specified for your release.
4. Retain db, config, diagnostics, account and licensing files.
5. Verify version, accounts, relationships and settings after launch.
6. Keep backups and logs if there is a difference.

This is general website guidance. The confirmed upgrade package defines the exact replacement files and compatibility scope.
