Thank you for this track !

This allowed me to find a solution to my problem : move a bound form after copying and moved his spreadsheet.

The Drive app advanced service must be activated in the "Resource Script Editor" to run this script.

function spreadsheetCopy() {
  // Below is the file to be copied with a bound form.
  var fileToCopy = DriveApp.getFileById("file_key"); // key is fileId
  var saveFolder = DriveApp.getFolderById("folder_key"); // key is folderId
  var currentFolder = "";
  ( fileToCopy.getParents().next() ) ? currentFolder = fileToCopy.getParents().next() : currentFolder = DriveApp.getRootFolder();  
  Logger.log(currentFolder)
  var copyFile = fileToCopy.makeCopy(saveFolder),
      copyName = copyFile.getName(); 
  Utilities.sleep(30000);
 moveFormCopy(currentFolder, saveFolder, copyName);
}

function moveFormCopy(currentFolder, saveFolder, copyName) {  
  var formsInFolder = currentFolder.getFilesByType(MimeType.GOOGLE_FORMS);
  var form, copyForm, copyFormMimeType, copyFormName, copyFormId;
  while ( formsInFolder.hasNext() ) {
    form = formsInFolder.next();
    if ( copyName === form.getName() ) {
      copyForm = form;
      copyFormMimeType = copyForm.getMimeType();
      copyFormName = copyForm.getName();
      copyFormId = copyForm.getId();
      break;
    }
  };  
  var resource = {title: copyName, mimeType: copyFormMimeType};
  Drive.Files.patch(resource, copyFormId, {addParents: saveFolder.getId(), removeParents: currentFolder.getId()})
}
