During upgrading OneFS from 8.0.0.3 to 8.0.0.4

Hi,

Our customer has a cluster  which consists of  S210&X410, and he is planning to upgrade OneFS 8.0.0.3 to 8.0.0.4, because there are many firmware problems on OneFS 8.0.0.3.

Before Upgrading OneFS, we are reading  "Upgrade Planning and Process Guide".

In the document, the following description are written on P.37

"Preserve the Kerberos keytab file"

Though our customer has been using the Kerberos authentification,

we can't find the /etc/ .keytab file and /etc/mcp/override/user_preserve_files.xml file.

In this stiuation,  do we have to do the procedure in "Preserve the Kerberos keytab file" section??

Regards,
