Hey there @Going.
If you are wanting to keep your Optusnet Webmail, this is an option you can look at.
In saying this, this would generally be for a customer who is cancelling their current Internet service or moving across to something alternative (Like 5G/4G Home Wireless).
But if you are looking to migrate your current Optus ADSL service to NBN, you will be able to keep your existing Optusnet webmail service active on the new plan that you end up choosing.
