My OES2 SP1/SLES 10 SP2 install sources are from NFS shares (ie: nfs://something.com/something)

After upgrading to SLES 10 SP3 and OES2 SP2, can I safely change the install sources so that it points to the SLES 10 sP3 and OES2 SP2 installs (ie: nfs://something.com/sles10sp3, etc.) and/or SLES 10 SP3/OES2 SP2 .ISO files?
