conversion ?

[Robert J.M. Edis]

G'day Joyce

I think the first decision you have to make is whether to redesign your
database from a hierarchical model to a relational model.  This will
seriously impact the amount of work to be done on the application programs.
Moving to a relational model will benefit your organization in the long, if
it's done properly.

Why are you migrating and what are your time contraints?  The HP3000 is a
FAR more stable and reliable environment than SUN Solaris, based on surveys
I've read.  TurboImage is a faster DBMS than almost ANY RDBMS.

Do you want to consolidate all your code, if possible, in a single language?
It is no problem converting COBOL programs to PH as long as you are prepared
for the paradigm shift in thinking how the problem should be tackled.

How much code are you talking about?
How will you convert your job streams into UNIX scripts?
What 'features' of MPE and TI do you use that are not available with
UNIX/Oracle?

Have fun.

Good Day!!!!

I need to hear some feed back from you guys, who had done a migration
from
 (HP3000/957) IMAGE DATABASE - SQL DB or Oracle DB on SUN Solaris
system. 

We are planning to do a conversion of our system. I would like to
findout
from
you guys, How hard it is? What is the best approach? Can we convert all
our
COBOL programs(to use micro focus) and powerhouse(?)? How long would it 
take us to do it? We have about 24g of records of our HP3000/957 system
now.


Thanks,
