The R3trans Program
The SAP transport programR3trans is used to transport data between SAP Systems and for the migration between different SAP releases.
However, note thatR3trans is usually called from other programs, in particular from tp ( Transport Control Program tp) and R3up (upgrade control program).
Therefore, direct use ofR3trans is only necessary in exceptions and is not supported other than in these cases. This R3trans documentation does not describe the normal transport procedure, but offers help in cases where the regular tools and methods are insufficient.
