Sharepoint local to Online Site

Question

Hi there,

We have a local web server, intranet.contoso.com. The DNS registries point to the server's IP.

Right now we migrate and create a new site called sharepoint.contoso.com/site/newintranet

The problem comes when we try to apply the change by modifiying only the DNS registries. Adding a CNAME, but we are not sure that the value sharepoint.contoso.com/site/newintranet would be valid.

Anyone can help us a bit?

Answer 1

So, you want users to access the new URL sharepoint.contoso.com/site/newintranet when they try to access the old one intranet.contoso.com, right?

• First, I think you typed the SharePoint Online URL wrong here, it would be contoso.sharepoint.com/site/newintranet
• You can also migrate your local site's content at the root of the SharePoint online site or make the contoso.sharepoint.com/site/newintranet as the root site
• I don't think this can be achieved by using CNAME entry as you ANAME needs to point to the IP address and SharePoint online is hosted across multiple IPs. You can use HTTP redirection hosted either on an on-premise IIS or on an Azure web site. Look at this article - Redirect to SharePoint Online URL using Azure web App - for more detail about this.

Hi @Eric ,

I want to confirm with you:
Do you want to migrate your SharePoint server to O365 SharePoint Online service? If yes, you can refer to @Anupam Shrivastava ’s answer.

Or you want to make your local SharePoint Server Internet access?

You can map a CNAME to the A record which is linked to SharePoint Server and configure AAM in SharePoint Central Administration.

In my case, I want to map "contoso.wendy.lab" to "sp13.wendy.lab".

Firstly I mapped a CNAME to the A record:

Then I configured AAM in SharePoint Central Administration:
