You can even configure what the mountpoint name will be.<BR /><BR />Example.<BR /><BR />I have the normal filesystems like /usr and I have one called /data<BR /><BR />/usr must be reformated to instal AS4. /data need not be reformated, it can be set up and untouched.<BR /><BR />Summary: Yes. You can. Read carefully, have a backup before you proceed.<BR /><BR />SEP Thu, 03 May 2007 04:42:15 GMT https://community.hpe.com/t5/operating-system-linux/upgrading-from-redhat-as3-to-as4/m-p/3992993#M64009 Steven E.
