i WANT TO MIGRATE SAP system of DB Size 75TB and 22TB , FROM HPUX/DB2 to LINUX/DB2.

We have a encountered a situation, where I would need your help to understand few things , that there is a SAP system of DB Size 76TB and 23TB , which needs to be Migrated from Source(OS:HP/UX DB: DB2) to Target (OS:LINUX DB:DB2).

I would need your help to understand some features of OS-DB Migration.

1. How much throughput can we expect in export ? How many GBs can be exported in a hour. In a system like this mentioned above, how much time would you normally plan for a downtime and why?
2. Is there any other process other than system copy (export/import) to move the Systems from one datacenter to another (OS-Migration).
3. Reference times for the export/import process, based on DB type/version, systems, quantity of data? (I understand it depends on the CPU-Memory the Server has, but any kind of benchmarking would be helpful)
