Why do we get an abend U3044 from the CA Top secret utility TSSXTEND?
z/OS
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 .
