Why do we get an abend U3044 from the CA Top secret utility TSSXTEND?
The old security files were defined with the AES feature. The new security files were defined without the AES feature.
It's not allowed to copy an AES secfile to a non-AES secfile, hence the abend U3044.
You have to defined the new security file with the AESENCRYPTION or AES256ENCRYPT TSSXTEND option .
