SQL-Server-2008

I try to export my data from SERVER1 to SERVER2. I try to get the latest date and not all the data in the SERVER1. The table I would like to move the table do content XML data type.

What I have tried:

SELECT * FROM OPENQUERY (SERVER1, 'SELECT  EmployeeID, EmployeeName, JoinDate, CAST([XMLContent] AS NVARCHAR(MAX)) FROM dbo.Computer.tblEmployee WHERE JoinDate=>'23-02-2016'  ')
								
		IF NOT EXISTS 
		(SELECT * FROM OPENQUERY ([SERVER2], 'SELECT  EmployeeID, EmployeeName, JoinDate, CAST([XMLContent] FROM dbo.Computer.tblEmployee'))
		
		BEGIN 
		 
		INSERT INTO dbo.Computer.tblEmployee SELECT * FROM OPENQUERY ([SERVER2], 'SELECT  EmployeeID, EmployeeName, JoinDate, CAST([XML] FROM dbo.Computer.tblEmployee')
		 
		END
