Hi list One of our sites has four AW51B's running Version 4.3. One AW is the CSA host and also hosts eight of the nine CP40's. A second AW hosts the last CP40. The other two AW's host x-terminals and are used as operator stations. There is a requirement to upgrade a CP40 to a CP60. Would it be possible, as an interim measure, to upgrade the two CP hosts to Ver 6.3 (to host the CP60), and if this is done what are possible pitfalls and what safety measures would need to be implemented to prevent problems?? Thanks for the help.
