Update 7.5.0.6

Hi All,

Is it necessary to uninstall 7.1 client software from linux machine to upgrade to 7.5  fllowed by 7.5.0.6 ? one of the sys admin tried to delete active SAP production servers binaries from (/usr/openv/netbackup) directory saying ,someone suggested her to delete and reinstall new version. I think deleting netbackup binaries in production doesn`t make sense .

Just want to know proper steps to upgrade from 7.1 to 7.5 .

Thanks
