Hi. Gurus.

I have two questions to ask you.

1) One of my customer wants to upgrade his SS20. It's running with informix
   DBMS and their custom application developed with cobol. And OS is quite
   old (2.5.1) My question is, is it possible to upgrade from old one to new
   machine with new OS while their application and informix have untouched?
   That is if we upgrade to new machine with new OS can we go with old
   cobol application with no re-compile and no-reinstallation of informix?

2) I have a E5500 with SunOS 5.6 system needing some care of performance
   tuning. But I don't have any formal experience to do with. Is there any
   standard operating procedure to tune a system?

Thanks in advance!!
Be well and always be happy!
