Migrating from auth0-js to auth-spa-js will logout all users?

I am following this migration guide: https://auth0.com/docs/libraries/auth0-single-page-app-sdk/migrate-from-auth0-js-to-the-auth0-single-page-app-sdk

After migration, will all my users in production get logged out? If not, what will their experience look like?

Is there any way that I can seamlessly migrate, without logging any user out?

Thanks

If you’re using Universal Login and Seemless SSO it should be transparent.
