Hi scythe944,
I talked with wpn about the removal process of old avast! 4.8 protection a few days ago. Basically avast! Business Protection should support some kind of upgrade for that, but since that is not supported (yet), you might try a half-automatic way.
- Deploy avast! Business Protection clients.
- Remove password protection from the clients by deploying this setting to the existing ADNM-connected clients using the ADNM computer catalogue.
- Remove the old 4.8 net client using msiexec (check uninstall string of the registry) silently by deploying this command by the domain group policies.
As far as I understood from wpn, both clients should work together on the same machine (haven’t tested that yet). At the moment I see the above steps as the only option available at the moment. Another way might be to have a more sophisticated batch script, which first uninstalls the old version and then installs the new version.
