Update drivers from a service pack that

Computer Associates wants me to update the IDEATA.HAM from ver 3.10g to ver 3.11 and IDECD.CDM from ver 2.00 to ver 3.00 for Netware 5.1. I have found these versions in service pack 4 for Netware 5.1. We are currently on Service pack 3 and are investigating service pack 4. If I extract the files and install them will they cause a problem without the rest of the service pack installed. They want us to update them to repair a backup problem which caused the SYS volume to dismount.
