Hi- I've been asked to upgrade a DEC3000 workstation (with 128MB and 2 internal and 4 external rz28 disks) from DU4.0b to DU4.0e or possibly DU4.0f. Is this a feasible project and more importantly, where might I find a good reference point for this sort of question in the future? Thanks Ken Cain MRSS/ESDU MCI Worldcom Colorado Springs, CO
