Hi Oz,
I regret for the long delay in getting back to you on this issue.
Yes, these steps cover the most required for the upgrade. Please refer the following document that shows how to configure the machine for the multiple installations(using both the 3.x and the 4.x versions).

For the sample browser issue, I will get back to you with an update tomorrow.
Thank you for your patience.
Regards,
Nanda
