Clean Installation - same IP address

The objective of this procedure is to install an entirely new instance of ERA Server that does not use the previous database, but retains records for client computers. This new ERA Server will have the the same IP address as your previous server, but will not use the database from the old ERA server.


On your current (old) ERA Server:

1.Export a server certificate from current ERA Server and save onto your external storage.

oExport all Certification Authority Certificates from your ERA Server and save each CA certificate as a .der file.

oExport Server Certificate from your ERA Server to a .pfx file. Exported .pfx will have private key included as well.

2.Stop the ERA Server service.

3.Turn off your ERA Server machine (optional).

On your new ERA Server:

validation-status-icon-warning IMPORTANT: Make sure the network configuration on your new ERA Server (IP address, FQDN, Computer name, DNS SRV record) matches that of your old ERA Server.

1.Install ERA Server using the All-in-one package installer (Windows) or choose another installation method (Windows manual installation, Linux or Virtual Appliance).

2.Connect to ERA Web Console.

3.Import all CAs that you have exported from your old ERA Server. To do so, follow the instructions for importing a public key.

4.Change the ERA Server certificate in your Server settings to use the Server certificate from your old ERA Server (exported in step 1.).

5.Import all required ESET licenses to ERA.

6.Restart the ERA Server service, see our Knowledgebase article for details.

Client computers should now connect to your new ERA Server using their original ERA Agent certificate, which is being authenticated by the imported CA from the old ERA Server. If clients are not connecting, see Problems after upgrade/migration of ERA Server.
