Requirement to map SharePoint 2013 Active Directory user with Azure AD

Question

I am working on a project where I need to migrate some of the Infopath forms manually from SharePoint 2013 to SharePoint Online. I have developed Console application to achieve this and it worked for other columns except UserField . Becuase Infopath's XML file is having a userentry as domain\\username and I need to convert it to SharePoint online user like username@abc.com..

I am not sure if this is achievable or not?

Any help is appreciated.

Thanks

About how to create user in SharePoint Online using C# code, Here are two solutions for your reference.

1. We can use the Microsoft Graph API to create User:

   Graph API create User

2. We can use Powershell and call it in our C# code to achieve this:

   Office 365: Manage users by calling Windows PowerShell cmdlets from C#

In addition, we can do sync on-premises directories: Integrate your on-premises directories with Azure Active Directory

Hope this is helpful to you
