We are planning to migrate websites to Netsuite.

Netsuite only provides CNAME record for their front end servers. They do not provide A records.

In Windows DNS that we use for internal environment, we have domain apex as “example.com”.
We can point the CNAME record from Netsuite to “www.example.com”.

However, how do I redirect the traffic so that when users type in https://example.com and it will get translate to https://www.example.com?

Do I configure an IIS server to point the apex “example.com” to the IIS server, and then configure redirect in IIS to redirect to https://www.example.com?
Will this cause any certificate issue when the website is migrated to Netsuite?

3 Spice ups

Oracle should be the ones to answer your questions regarding the NetSuite setup process. However, you could point the A record for the root to your own server that does a redirect or they may require pointing the entire DNS zone to Oracle at the registrar. I’d host the redirect on Linux and usually only use Windows hosting for websites that require it.

The certificate needs to be setup by either by uploading your own that have purchased or the option to generate via Let’s Encrypt or Oracle – again, ask their support.
