Upgrade Netbackup client from 7.0.1 to 7.5.0.5

I need to upgrade Netbackup client on 64-bit Linux server. The current client version is 7.0.1. I am not a system admin so need some guidance on how to proceed with the upgrade. These are some high level steps that I have come up with.

 

Download and join NetBackup_7.5_CLIENTS_tar-gz.1of3, NetBackup_7.5_CLIENTS_tar-gz.2of3 and NetBackup_7.5_CLIENTS_tar-gz.3of3 into NetBackup_7.5_CLIENTS.tar.gz.

 

#/etc/init.d/netbackup stop

 

#tar zxvf NetBackup_7.5_CLIENTS.tar.gz

#cd NetBackup_7.5_CLIENTS

#./install

 

This should upgrade the Netbackup client from 7.0.1 to 7.5. Now I download and join the NB_CLT_7.5.0.5_tar-split.1of3, NB_CLT_7.5.0.5_tar-split.2of3 and NB_CLT_7.5.0.5_tar-split.3of3 into NB_CLT_7.5.0.5.tar.

 

#tar xvf NB_CLT_7.5.0.5.tar

#./NB_update.install

 

#/etc/init.d/netbackup start

 

Do these steps look correct? Have I missed something? Any guidance will be appreciated.

 

Thanks.
