There is one known issue when upgrading from OpenROAD 5.1 to the current version that involves copying or creating database connection profiles. When you upgrade from OpenROAD 5.1 to OpenROAD 6.0 on newer 64-bit Windows platforms, the path to database connection profiles changes. You must copy OpenROAD 5.1 profile files to the OpenROAD 6.0 directory or recreate the profiles when you start Workbench.
