NPM and IPAM update

Hi guys..

We are running NPM 10.3 IPAM 3.0 and there is an update availabl NPM 10.4.1 and IPAM 3.1.

I'm new with this system. Not sure what steps should I follow to update or if this is very straight forward, just download locally the update and run the wizard..

how long could take this?

how can I do a backup prior updating?

what other information do I need, database account?

thanks
