First, ensure your Magento version and vBulletin 5 Connect version are compatible, as outdated versions may cause integration conflicts.
Download the latest vBulletin Integration extension for Magento and check its codebase for compatibility notes.
Identify the authentication system in vBulletin 5 Connect, since its login/session management differs from older versions.
Update the PHP scripts of the integration to use vBulletin 5’s new API hooks rather than deprecated ones.
Replace outdated database calls with vBulletin 5’s recommended model-based queries for user data handling.
Ensure proper session sharing between Magento and vBulletin by syncing cookie parameters and domain settings.
Modify the user registration flow like sim in Magento so it pushes new users into the vBulletin 5 database structure.
Test password hashing methods, since vBulletin 5 may use a different encryption standard than older versions.
If errors occur, enable debug mode in both Magento and vBulletin to trace issues during login/registration sync.
Add a SIM test environment where you clone both platforms and experiment with PHP edits before going live.
Document every change you make in the extension to ensure easy updates or troubleshooting later.
After editing, perform thorough cross-platform testing (login, logout, registration, and profile sync) to confirm everything works smoothly with vBulletin 5 Connect.
