SCO unix 5 to 6 Migration steps

[wsowss]

We are going to migrate our current application to an updated and supportable SCO (verison 6 or later )environment. I would really appreciate if you could provide me some more detail about migration steps for Cobol programs as well as JCL and VSAM files. Do I need to re-compile all our current application to newer version of SCO. I would really appreciate if you could send me the SCO UNIX 5 ot 6 Migration steps or any document..I'm very new to SCO unix.. I would really appreciate your help

Thanks

What COBOL vendor are you using?
COBOL Files, regardless of the vendor can just be copied.

And by JCL I take it you really mean shell scripts?

Noone here knows about SCO
Who have installed your old server and/or the application ?

Hope This Helps, PH.

Regarding your system, as you don't have anyone inhouse with knowledge of it I STRONGLY advise you to hire someone to do the OS migration. If you state your country (and state if required) its possible someone here on forum could recommend you someone to do the work.
As for documentation should you wish to do it yourself, have a look at

http://www.sco.com/support/docs/openserver/

It contains all you require.


Regarding your application.
With RM/COBOL the only thing you need to do is to copy the programs (objects), and source if your doing the development yourselves. If not then it should be your vendor dealing with the migration.
No need to recompile, but if you are buying a newer version of the compiler/runtime, there may be some benefits on doing it depending on your current version. Depending on your current SCO unix version you may or not be required to upgrade your COBOL compiler/runtime.

As for the datafiles, just copy them over. No conversion needed within SCO.

Only thing you may need to worry about, is with system definitions, and these are NOT related to the COBOL application, but rather to the OS itself.
Things that come to my mind is that printing defaults changed in some versions of SCO, and some switches were required to add to the cobol configuration files, or indeed to your printing programs, in order to get the spooling of the files working. This may not be a problem to you depending on how your print. Again, this is not COBOL related.
