Our customer has a cluster which consists of S210&X410, and he is planning to upgrade OneFS 184.108.40.206 to 220.127.116.11, because there are many firmware problems on OneFS 18.104.22.168.
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/<name>.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??
