We are upgrading a classical SAP Landscape (Development, Quality Assurance, Production) from 4.6c to ECC6.0.
The problem is that, in parallel, a separate HR project is taking starting to enable payroll on a separate development system.
The standard landscape must remain untouched untill end 2007 (end of use of present external payroll)
On january 1st 2008, we are supposed to merge the standard landscape with the developments made on the separat HR project to include sap payroll.
Classically, parallel development is always a problem. Reconciliation is normally recommended via serial positioning; in other words, the new HR dev system is positioned before the standard dev system in the transport routes to avoid object collisioning.
Does any of you have a practical experience of such a situation which could be shared among us ?
Thanking you in advance for your cooperation.
