Upgrade

Hi All,

I'm in the middle of upgrading our database now.

Our Source DB details as follow :

RDBMS Version : 11.2.0.3

Host Server : AIX 6

Target details :

RDBMS Version : 12.1

Host Server : Linux RHEL 6.0

DB Size : 250GB

RAC : Yes

From the early discovery it seems we will choose to use datapump, this is because we consider that the target and source endian is different. Hence it will be much easier for the datapump ?. Although I'm still open to new idea.

Question are :

1. Can we use full export/import including system schema from the source to the target ?. Or the best practice is to use schema export/import and leave the system alone.
