Upgradation Techincal in ess
there is an upgradation technical in ess ,
here the issue is we have all the objects which were customized in 4.6b and the upgradation is to ECC 6.0 .
while upgradation the coding for the changes made( upgradation) from 4.6b to ecc 6.0 should be made in Webdynpro Abap or Webdynpro Java.
for the customized objects can we use Webdynpro Abap rather than webdynpro Java.
In the J2EE server can we install Webdynpro ABAP and use it further .
please reply me at the earliest possible.
