Server Upgrade

Hi

I actually
ESET Remote Administrator Server version 3.0.142 and ESET Remote Administrator Console installed on a domain controller
around 200 clients connect to this server for virus updates

I downloaded 4.0.138 for server and console

What steps should I follow for upgrading?
Just launch MSI file? Console first then server?
Or first uninstall product?

How to upgrade clients too after that?

 

This KB Article should cover the entire process for you from start to finish:

How do I upgrade my network to ESET server / endpoint products? (5.x)

 

I'd suggest using the latest version of ERA 5 which addresses reported issues and also supports new features added in Endpoint products.

 

Nothing is told about compatibility of V4 client and V5 server
Is this possible to keep a mixed environnement during a few weeks?

(Would be really hard to migrate thousands of clients machines and servers in a short time)

 

VersionCheck on server only told me that new version is 4.0.138
Impossible to upgrade from 3.0142 to 5+?

 

I am not sure about upgrading from v3 to v5, however when I upgraded our server and system from v4.2 to v5, I upgraded my console version first on my local machine. After that, the console told me that it could not communicate with the server any longer. So, I upgraded the server.

All my clients and other servers are still v4.2 and are still updating their virus defs.

I am doing a slow rollout of my clients first to v5 before I do my servers. I figure I will take a month to upgrade all 1,000 machines.
