- We are trying to decide what strategy to use in porting our product
- to new platforms. First let me describe our product :
-
- - Developed on HP-UX.
- - Two years old.
- - Written in C++ with Motif.
- - Uses HP's Allbase RDBMS.
- - Uses the Tool Integration Platform architecture. (ie. Socket-based message
- passing.)
- - Approximately 150,000 lines of code.
- Note : since this was our first large project with OO methods and C++
- we think we can do things differently now.
-
- We anticipate the need to port to Sun and IBM platforms and use other
- database engines as well.
-
- I have the following questions :
-
- 1) Have you used a contractor who specialized in porting? If so,
- what was your experience?
-
- 2) How difficult is it to port to Sun, IBM from HP-UX?
- - For a group only experienced with HP-UX.
- - For a group experienced with Sun and IBM.
-
- 3) Is there a source/guideline document anywhere that could be used to
- help us through a porting effort?
-
- 4) What is a rule of thumb in estimating a porting effort? For example,
- a fraction of the original development time, an estimate based on
- how many lines of code, etc.
-
- 5) How critical is it that the person(s) doing the porting are actually
- familiar with the code? If they are not familiar how much longer
- will it take them?
-
- Thanks,
-
