Hi @Mohammad Tahir , thank you for posting in the Q&A forum.

You can refer to the document here (previous Microsoft KB) for how to upgrade a server operating system that has SharePoint Server 2013 or 2010 installed.

Microsoft does not recommend performing an in-place upgrade of Windows Server.

For the SharePoint servers, create new servers with Windows Server 2012 R2, deploy SharePoint, configure it appropriately, rotate it into the farm, and then retire your older SharePoint servers.
For SQL Server, also build a new server, migrate the databases + SQL logins and retire the old SQL Server.
