Answer Posted / seshadri reddy
There were somany instances as depicted below:
1.If the customer was using some old version of oracle
Aps,If he wants to switch over to the new version.If the old
version structure is no compatable to the new version.Then
we have to transfer the data from old version tables to
flat files again from there we have to upload into the new
tables.
2.If the customer is using more than one application for his
total enterprise,since every module is interlinked we have
to transfer the data from one module to to other.In this
case we cannot transfer the data from one application to the
other directly.In this case we have to get the data into
flat files and tranfer into the next application..
