MicroFocus COBOL migration 3

[gocobol]

Hi everybody,

This is my first post ever in this forum. Hope that I didn't ask too much.
We have a system here running MicroFocus V4.0, Solaris 2.5.1, Oracle 7.3.4, ProCobol 1.8.4; and would like to upgrade to ServerExpress 2.2, Solaris 2.8.0, Oracle 9i.
Just wondering if it is feasible to do it without the pain of modifying most of the COBOL and PL/SQL codes? Is there anything to be aware of in terms of the compilation of COBOL codes under new operating system environment and database setup?
I'm entirely new to do this kind of migration, any help and directions in detail will be much appreciated!

Many thanks in advanced.

Best regards,
Jean.

Hi all,

I think I could be posting to the wrong forum.
Can someone please tell me where is the right forum to post this kind of question?

Thank you.
Jean

Jean,

Your question(s) is so broad, that short of migrating that stuff for you, I don't see how anyone can address it.

There are too many variables in your questions: different OS, different DB, and god knows what else. What can I say, you have your work cut out for you.

See if there is anything you can do by yourself. If you run into a specific problem, I am sure someone will help. You can also hire one our experts to help with the migration.

Hi gocobol,

I don't know the systems you are using so cannot comment on the particulars but have in the past done several migrations of Cobol code across (mainframe) environments and it can be very difficult - there are lots of minor differences between compilers which can make major differences to the end results of programs.

It's not clear (to me) what is changing with respect to your Cobol - are you moving to a new compiler or just a new runtime environment for your Cobol programs? My advice would be to avoid, as far as possible, recompiling ANYTHING - if that's not possible, then I'm afraid you'll probably have to do a lot of testing.

I'm not an Oracle expert, but I would expect very few changes to be required because of the Oracle upgrade, and also would expect Oracle documentation to highlight them. There are several Oracle forums here if you have specific questions on that front.

The other systems you mention are alien to me - I don't even know whether there are fora here for them, but it's worth having a look at the forums list.

Enjoy,
Tony

Hi, thank you for the reply and precious advices.

Yes, it shows no doubt that there will be many difficulties since we are moving the system to a new UNIX box and upgrade the OS from Solaris 2.5.1 to 2.8.0, DB from Oracle 7.3.4 to Oracle 9i and ProCOBOL compiler from MicroFocus V4.0 to ServerExpress 2.2..

Now What I concern most is the huge differences (maybe yse? maybe no?) between MicroFocus V4.0 (10 years old version) and ServerExpress 2.2, so far I don't have much information or documents about this, so I wonder what kind of monster it will be when compiling the COBOL code.

But In the meantime maybe the best way is "Try it step by step" and then see what's happen. Thank you again!

I'd be optimistic:

- MF cobol is backwards compatible (I know)
- Oracle ... well, I doubt you use funcions which are not supported in the newest version (I guess)

Solaris v.s. solaris. Depends, is the one 32 bit and the other 64 bit? If so, are there many calls from cobol to unix-api's or do you use "CBL_" routines? (CBL_ = no problem)

Please keep us informed in this forum about your findings & progress.
