Use official migration resources and test dependencies that still rely on Vue-3 support.

Code Example: Pinia 3 in Vue 3 App

// store.js
import { defineStore } from 'pinia'

export const useSampleStore = defineStore('sample', {
  state: () => ({ text: '' }),
  getters: {
    uppercase: (state) => state.text.toUpperCase()
