# Migrating

Notes on migrating from previous version of Vinoshipper Injector: Club Registration.

If you are [transitioning from a previous version](injector-transitioning-from-previous-versions), the following notes will be helpful.

# ID → Class name

V3 used the ID name `#vs-wineclub-signup` to define the element, which causes conflicts with multiple instances of a cart. This was changed to the class name `.vs-club-registration` so more than one instance may be displayed.

# No CSS injection

Previously the cards settings was based on injecting a complete CSS file reference. Please refer to [Styling](club-registration-styling) for more information.
