Renaming Transformers
If Integration Server displays the message “Transformer not found” when you try to expand a transformer or when you point the mouse to the transformer, then the service referenced by the transformer has been renamed, moved, or deleted. You need to change the Service property of the transformer so that the transformer points to the moved, or renamed service.
If the service referenced by the transformer has been deleted, you may want to delete the transformer.
To rename a transformer
1. Use Package Navigator view to determine the new name or location of the service called by the transformer.
2. Open the flow service containing the transformer you want to rename.
3. In the flow service editor, select the MAP step containing the transformer. Then, in Pipeline view, select the transformer you want to rename.
4. In the Service property in the Properties view, delete the old name and type in the service’s new fully qualified name in the folderName:serviceName format, or click 
to select a service from a list.
