Upgrade to 9.41 Hybrid path

I have 9.31.3009 using Windows client exclusively.

Can I load PDCP 9.30.3 (Pack 3) as a step to upgrading to 9.41 Hybrid?

What will I need to change?

Can I keep my format controls and display options for the modules included in Pack 3 which I believe are Knowledge Mgmt, Service Level Mgmt, Change Mgmt, Problem Level Mgmt, Incident Mgmt and Service Desk. Did I miss any? Are there any others? :-)

Thanks Patrick
