https://community.hpe.com/t5/operating-system-hp-ux/porting/m-p/4357581#M667530 I have ported software written in C++ from Tru64 to HP-UX 11i v2. I have used the Migration Environment for HP-UX 11i v2 (because this was the only version available)<BR />and the Developing_Bundle_11.23. I have to run now this compiled software on a server with HP-UX 11i v3. Is this possible with out problems.<BR /> Thu, 12 Feb 2009 17:23:04 GMT Berardi Angelo 2009-02-12T17:23:04Z https://community.hpe.com/t5/operating-system-hp-ux/porting/m-p/4357581#M667530 I have ported software written in C++ from Tru64 to HP-UX 11i v2.
