Merging a SAP System with another SAP System
We have requirement to merge one SAP system with another SAP system. In this context we have to migrate all data ( control, master and transaction data) from one system to another system also we need to copy all custom programs, custom routines user exits, routines etc..Without any discrepancy to the existing both systems process.
If anyone did this kind of project earlier please let me know what could be the best approach and how to go about it. I would appreciate if you would share any documentation on the same.
I know SAP SLO (System landscape Optimizer) tool is there for the same but we are not going use that in our project.
Thanks in advance.
