Upgrade from 7.1 to 8.5

Hello,

A client of ours is in the process of upgrading their SuperOffice Web installation from 7.1 to 8.5. The question my contact would like to know is if there is a way to automatically push the updates out to all the users or if each individual user needs to install the web tools manually. I seem to remember that an upgrade to some versions requires the complete removal of the old web tools before the new ones can be installed.

My question is whether pushing out an update to the 8.5 webtools is possibe and do the old 7.1 webtools need to be uninstalled first.

Thank you,

Brian
