Install netbackup on new server

Hi All

I'm planning to install the netbackup server on new hardware

The current net backup version is 7.5.0.6. I need to install and upgrade to lastest version 7.6 on new server

Could you please help to share step to do that without impact to current catalog?

Do we need to reinstall 7.5.0.6 on new and then upgrade or install 7.6 directly

Thanks
