If you are using ADNM now, you already know 90% of ADNM2, and may want to wait for that version to be released with its final patch for the mirror. It can be installed today, Ed has the URL for the patch, and you will have to apply it. AEA is the same reliable code from ADNM, with the added features of the avast! 7 net client. There is very little different from the previous version. The only major difference is the combining of Computer Catalog, and Task Management module into the same location (they were separated before). During installation, you are prompted for choice of SQL 2008 R2 Express, or use existing install of SQL. If you have either SQL 2005 or SQL 2008, you can use same instance, but a NEW database will be required, as new modules are supported. Their is no conversion utility for the old database at this time, so you treat it as a new install. Both ADNM and AEA can exist simultaneously. Net client auto uninstalls the existing avast net client vs. 4, and installs new client. WE will NOT have to touch every machine (we really needed that). After AEA installs, it is recommended to unplug Internet before deploying the new client. That way you are not online during this moment when there is no A/V protection. The avast! 7 net client does require a reboot after installation (all protection is not immediate upon installation). Each avast! Enterprise Administration Server (old AMS, now AEAS can manage 1000 systems. However, full SQL is required for the “Replication Service” to support multiple AEAS (to support 1000+ systems) AND again, there is no migration path currently that will use the existing database.
