The following table outlines some considerations you should be aware of before switching the scan method that OfficeScan agents use.
Number of OfficeScan agents to switch
Switching a relatively small number of OfficeScan agents at a time allows efficient use of the OfficeScan server and Smart Protection Server resources. These servers can perform other critical tasks while OfficeScan agents change scan methods.
When switching scan methods, OfficeScan agents need to download full versions of the required pattern files for the new scan method.
Consider switching during off-peak hours to minimize the impact to network bandwidth and interruption to end user daily operations. Trend Micro recommends disabling "Update Now" on OfficeScan agents during the conversion process.
Agent tree settings
Scan method is a granular setting that you can apply on the root, domain, or individual OfficeScan agent level. When switching the scan method, you can:
Create a new agent tree domain and assign conventional scan as its scan method. Any agent you move to this domain will use conventional scan. When you move the agent, enable the setting Apply settings of new domain to selected agents.
Select a domain and configure it to use conventional scan. Smart scan agents belonging to the domain will switch to conventional scan.
Select one or several smart scan agents from a domain and then switch them to conventional scan.
Any changes to the domain’s scan method overrides the scan method you have configured for individual agents.
