Hi All, We have a ADABAS / NATURAL code base (with CICS screens) talking to DB2 database. Also there are JCL programs running via ESP scheduler. This complete solution is hosted on IBM’s z/OS (Mainframe). Our requirement is to re-host this complete solution on UNIX boxes. I would like to know - at a high level - what would be the steps involved? Also, what are the possible roadblocks that we could encounter during this re-hosting exercise. I understand this is a quite a huge effort. So any help on this will be highly appreciated. Thanks in advance, PR ---

The effort is not that huge or complicated. The main consideration is converting all your mainframe JCL. You will come across a multitude of minor issues but none should stop the project. Most utilities you might be familiar with on the mainframe have equivalents or near equavilents available on other platforms. ---
