Computers may update differently
When you migrate computers, the way they get updates may change.
In Sophos Central, computers download their updates directly from Sophos by default. This can increase your bandwidth usage.
Consider using the Update Cache feature in Sophos Central. This allows you to set up "update caches", which store updates on a server on your network from which computers can download them. We recommend that you do this before migration to avoid spikes in bandwidth usage.
