RPG to c#

I need to prepare a requirement for a vendor and they are going to take our AS400 DB2 iSeries RPG program and convert into c# and allow our classic asp website to consume the program.

What should I construct the document? If you have experience working this in the past, please share with me.

Thanks

I've done similar conversions.  

But usually, a full conversion from RPG to C# is unnecessary.  It is often very easy to remotely run IBM i / iSeries / AS/400 programs from an ASP web site - often with little or no modification or conversion required at all.  

Of course it depends on the program.  Perhaps you could share a little more information.  Is this an interactive RPG program, or a batch program?  What does it do, in general?  

What version of the IBM i operating system are you running on your system?

In general, you want to carefully describe the technical and functional requirements, and make sure that the vendor understands completely the requirements.  You also need to be careful to provide performance and security requirements - I've seen specs developed that didn't specify performance and security requirements (especially important in cross-platform applications, or applications that may expose your system directly or indirectly to the internet) that were completed and signed off, and then required extensive re-work to meet performance requirements and to secure the application properly.

If you aren't familiar with developing these types of specifications and requirements documents, you might want to bring in an experienced consultant to help with requirements development and to help you put together a specifications document.

It is AS400 DB2 iSeries and the database will be retired within 6 months.
And we already export data to MS SQL Server.

We just need to know what inside of RPG so we can convert into combination of c# and stored procedures.

Makes sense.  Does your vendor have good RPG skills?
