Best approch to uninstall office 2010 and upgrade to Office 2013 in one deployment

Hello All

I created a package in sccm 2012 to remove office 2010 and a separate package to install office 2013. Now I know I can use the feature to run one program before the other but I think a reboot may be required after uninstalling Office 2010 before the Office 2013 installation can start? Does this seem off base? It would be pretty disruptive to our users if this is the case

Any advice would be greatly appreciated.

Thanks
