Page 2-1 of the 5.5 communicator states: "To update or install MPE/ix Release 5.5 (C.55.00), your system must already be on the MPE/ix 4.0 (B.40.00) or the MPE/ix 5.0 General Release (C.50.xx)." The operative word is 'install'! Does this mean that if I want to put 5.5 onto new disks that I first have to install my previous 4.0 or 5.0 versions?
