Preprocessing phase and Execution phase of DMO

68 Views

Hi experts,

I have a question.
Please tell me whether my understanding of DMO procedure steps of Preprocessing phase and Execution phase is right.

I think as below.


Phase



sequence



Steps



whether users can
log on SAP system or can not



whether
application data is able to be changed or not



Uptime or
Downtime



Preprocessing



1



Creating Shadow
instance



Users can log on
ERP



Application data
is able to be changed



Uptime





2



Creating Shadow
repository



Users can log on
ERP



Application data
is not be able to be changed



Uptime





3



Migration
repository



Users can log on
ERP



Application data
is not be able to be changed



Uptime



Execution



4



Migration
application data



Users can not log
on ERP



Application data
is not be able to be changed



Downtime


When creating shadow instance, users can log on SAP system and can change application data.

When creating shadow repository, user can log on SAP system but can not change application data.

Both when creating shadow instance and creating shadow repository ,users can log on SAP system.

So Preprocessing phase is uptime .

Is that right ?

Thanks in advance.

Best Regards,

Kazuki
