Following instruction from KB000009558, the step C failed with errors;
IDC3302I ACTION ERROR ON targetbdamname
IDC3309I ** RECORD X'0000000100' NOT WRITTEN. LENGTH INVALID
The issue seems to come from the target BDAM file, the LRECL is not equal to the page size of the original ELIB.
If PAGE = 4088, the BDAM file must be define with the same LREC, i.e. DCB=(DSORG=DA,BLKSIZE=4088,LRECL=4088,RECFM=FBS)
