I need to move the application from the c drive to another disk

I need to move the application from c:\inetpub\wwwroot\filevista to w:\www\filevista.  I tried copying the files and updating the document folder settings, but that did not work.  

There shouldn't be any problems if the database path is stored as a relative path (~\App_Data\database\FileVista.mdb) in ConnectionString setting of App_Data\FileVista.config. Please check this path.

Do you get any kind of errors?
