The problem about changing the SID

[Former Member]

Hello,

Due to some reasones ,we shoud chang the R3 sid from PR3(instance number is 00) to QR3 on one IBM iseries host .As we read some relatives doc about system copy ,we decide use method of exoprt/import to do this.But there are paramter that really confuse me now.In the step of SAP system instance indentification,I hesitate the instance number should be set.Should I choose a new number or keep the value that PR3 used(instance number is 00).

BTW,is there two instance or just one instance in the host after I change the system sid.

Thanks in advance.

This problem I understnad now.But still one got me.

I want to use SMIGR_CREATE_DDL to generating ddl statements for migration,but when I finished this ABAP I cann't find any script has been generated.

The installation Directory is '/tmp'.

Our platform of R/3 is OS/400.

Thanks.
