Domain is in GoDaddy and Hosting is BlueHost, Is it ok to Migrate?

@jerichomontes Thanks for checking our tutorial.

Answers to your questions:

1. Yes, those tutorials working fine. Only we haven't updated screenshots (which are old now).

2. You can use same godaddy domain registrar as well and hosting with bluehost. Just make sure after content migration is successful you can change the DNS records in Godaddy to point correct IP of bluehost hosting account.

Thanks.
