PHP → SIPL
Choose the backend.
Keep using PHP while you test the native SIPL implementation. Each backend has its own sign-in session.
CURRENT IMPLEMENTATION
PHP
The existing site and installer remain available.
PARALLEL IMPLEMENTATION
SIPL
Uses the same MySQL schema and endpoint contracts.
Start the SIPL server, then check its runtime capabilities.
Switching opens the other server. It does not copy sessions, change the database schema, or silently forward SIPL mutations to PHP. Save your edits before switching.
