Symptoms
After cluster upgraded from 11.2.0.4 to 12.1.0.2 containing encrypted ACFS filesystem,reading encrypted files stored on ACFS file systems returns incorrect data.
We see some unrecognisable characters in those files which were specifically placed before upgrade with encryption.
New files after upgrade looks in proper shape.
This impacts only for 11gR2 ACFS encrypted filesystem while upgrading to 12.1 .
Example of one file with corrupted contents, file created before upgrade:
$ cat /XXXX/CSS/logs/20151109_mms_PROCS.log
