Vendor provided software can be put under Endevor as object type. Create the new type as delta format of I (Image) source length of 32000. I have compare FROM 1, with compare To=1
Processor would consist of BSTCOPY step from an external library into Endevor protected library with keyword of Footprnt=create on the output statement.
Then it can be migrated like any other type.
Hope that helps,
