ECC 4.6 c to ecc6.0
We have web dynpro applications running smoothly connecting to ecc 4.6 c r/3 system via Jco destinations.
Their are plans to upgrade r/3 to ecc 6.0 .
Will this have any impact on existing applications or portal behaviour.Or any changes in the behaviour of bapi themselves.Few questions that come to me immediately are ..should Jco be redefined should models be redefined..etc
Pls let me know.Also point me to the right info.
