Good Day
#1 - There may be legal implications to this that drive technical requirements; make sure the EF *and* the XYZ lawyers both approve the conceptual solution.
#2 - Aspects of #1 may be entirely Functional in scope (General Ledger changes, I'm thinking), which again may drive additional technical requirements.
I agree with Rich. Lowest effort approach is to copy the whole system and then start to archive the (respectively) newly irrelevant parts on each side. I have no doubts about the feedback in #1/#2 adding considerably to your work.
Otherwise you'll end up exporting EF's master & transactional data from the existing system and loading it (trying to load it) into a newly installed system, which I'm guessing will take far longer overall and with much more user-perceived system downtime (you wont want users on the system while you're mass loading & verifying data loads). The functional effort will be far less in the system copy approach than it will otherwise. If you end up having to go the export/import route, a 3rd party tool like infoshuttle might help you reduce the time that it takes.

Subject: Complex Migration Scenario for SAP ECC 6.0
Hello Gurus,
Good Morning !!
We have a requirement where there is a "Parent Company" say XYZ and it has various sub companies like AB, CD, EF.
Now EF has decided to move out of XYZ umbrella for whatever reasons.
EF has all it's data in the 3 system landscape . DEV-->QA-->PRD.(client 100 across all the system), which is being shared/used by other sub groups also like AB and CD. i.e multiple Company codes in 1 client.
EF has decided to have it's own SAP system environment (3 System Landscape).
We have to carve out data specific only to company EF from the single client itself.
My query is
1) Is it possible to Migrate only data specific to EF from the common client ? If yes, then how ?
2) If no, what can be the work around.
All the systems have OS: Solaris , DB : Oracle
They want to migrate to Windows server 2008 and MS SQL Server 2005
Is this possible ?
Had this company's data been in separate client , even then how would we be able to migrate this data to new OS and DB ?
I am not sure if client copy taken from ORACLE to MS SQL SERVER will work or not .
This seems to be a bit complex scenario, so i need your expert opinion.
I would also like you to suggest me how much time would this activity take in both the scenario taking in "Buffer Time". i mean how many days should at least a DEV system will take to Migrate to new OS,DB(Server), their approx DB is 400GB.
Thanks in advance.
Regards,
Cyrus. |
