Updating an old Sophos install

Hello,

I work for a small research institution. I just started, and there are a lot of things that need updating to bring them up to date here. One of them is Sophos. Currently sophos is installed locally on every machine, and they all reach out and update the virus definitions individually. I'd like to transition from that method to a server based method where it updates and they all leach virus definitions and settings from it.

I'm having a hard time finding documentation on the best practices and installation instructions in this regard. Where would I find these? What tips and tricks/settings should I use to make sure everything is running well and keeping the computers here safe?

Thanks for your help
