Hello Michael,
In the first post here you have said that you have upgraded from 9.1to V10.0 5520. So naturally you are planning to install the SP1 from V10.0 5520. Here is the link for the same:
http://support.veritas.com/docs/278701.
This states that the remote agent needs to be reinstalled on the remote servers after the installation of SP1.
The link suggested to you earlier by Steve is for V10.0 5484 and hence does not apply to you!!
