r3setup dbexport with parallel import
I am planning a heterogenous system migration using a database export.
(R3SETUP DBEXPORT) for SAP 4.6B (UNIX - DB2)
The database size is 400GB big. After this export and import I also need to upgrade to ECC 6.0
If possible during 1 weekend
So some questions for people who have already done this before:
1. Is it possible to start the installation of the new 4.6B system using IMPORT files when the EXPORT is still being processed ? I heard this was possible but I did not find any information yet. Of course we need to use several files instead of 1 big file then.
2. Who can estimate how big my DB export will be ? DB2 V6 size = 400GB.
3. I have no choice but to dump on a networkshare (NFS) as there is not enough local storage. Will this cause problems ?
Thank you for your time !
