Just a few points from my side: How do you plan to handle workload and response time on a server farm while ensuring no deadlocks can take place? DB2 and CICS have good measures to ensure no two records are updated at the same time while keeping security and availability as top priority. >The customer run Z/OS 2.1 and CICS TS 5.x and DB2 version 11. How many transactions are done per day and how many [active] users are working there? Can the 'new' server farm' and all the network resources handle the workload easily? We have for CICS, for example, about 30 to 60+ million transactions per month, I don't know how many are there for DB2 and other database systems. And we are "small". I don't think it was mentioned in this thread, but a regular complaint I see is - when the workload grows, you need to add more servers (with enough aircondit and electrical feeds) and disks to handle the load while z/OS hardware has already spare CPUs (and memory) available (if installed) waiting to be activated as per Big Blue agreement. >Have anybody experience with the vendor MetaWare doing migration , >Did they succeed in migrating.

Granted, you need to register (which I did not, because I am not in the mood to receive spam e-mails), but you probably will only see glowing testimonials and praises for MetaWare.

I believe there are similar things for that. Ask them too whether they have products doing what HSM and SMS do? Oh, ask them whether they can handle (on the server farm) Crypto and transactions/sessions using SSL and friends. I know these servers can do that in a way, but how do they that? And how fast (4K blocks per seconds for example)? Last question - ask them about backward compatibility.
