Hey Dude.,

First you want to create the Database in SQL SERVER which have same schema of your current Access database
Second then replace the name space where you used System.data.OLEDB name space into Syatem.Data.SQLclient
third thing change the oledbconnection to SQLconnection , Oledb command to sqlcommand,and oledb related object into sql server related object

Note: use second and third in Front end,first only in SQL server
