3. The Copy Library Aliases page appears; select the Current Original Value to enable the additional fields on the page.
   Note: Click Change Account to change the Account Id.
4. Enter a value in the New Original Value to Copy Permissions to: field. The end of the value should include /(.*) or \(.*).
5. Enter the New Destination Value to Copy Permissions to: field.
6. Click Update Aliases. All accounts that had access to the current library will be granted access to the new library and aliases will be created.
