I don't get it..The old system is written in cobol, it stores data in a complex way built apoun years, and fo this reason to do simple thing its a pain in the ass ok. So one have to design a new system, with a "modern" technology approach, that doesn't need to be similar to the old, it has just to be good, safe easy to maintain. Then populate the new database from the Cobol's one (i have to know which kind and type of data i need in my new current system). run and test the new system as soon as everything works fine, then shutdown the old one. In the end it s not just extract all the data and inject it in the new system? Am i missing something?
I’m assuming you have never done any of those things. So yes, you’re missing quite a bit.
