An application is upgraded and it has been determined that the AccessAgent no longer properly responds to the application. It is understood that for a certain amount of time both the current version and the upgraded version of the application will be used by the end-users. The executables for both versions are the same. What should be the next step？（）

A. Open AccessStudio and change the existing AccessProfile to use only the new signatures for Windows， control IDs， or HTML elements.
B. Open AccessStudio and create a new AccessProfile for the upgraded version and overwrite the existing AccessProfile on the IMS Server.
C. Open AccessStudio and edit the existing AccessProfile by using new triggers/actions associated with the new signatures for Windows， control IDs， or HTML elements.
D. Open AccessStudio and create a new AccessProfile for the upgraded version and upload it to the IMS Server so that two separate AccessProfiles may be used by the AccessAgent.
