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

I am following this migration guide: 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.
