After selecting which validation rules to merge, this step enables you to either overwrite the source class script with the destination class script, or leave the script as is.

You have the following settings:

Keep destination class script

Does not copy the class script from the source project to the destination project. If there are any elements that rely on the script, they may not work as expected.

Overwrite with source class script

Copies the class script from the source project and overwrites the destination project. The project script may need to be updated if it refers to elements in the class script.

After selecting whether or not to merge the script, click Next to proceed to the next step in the wizard, or click Cancel to exit the Project Merge Tool without merging the two projects.
