Issue

• Upgrade individual ERA components (Agent, Server, Proxy) to the latest ESMC
• Resolve CReplectionModule errors by upgrading to the latest version

Solution

• Upgrade ERA Server using the Components Upgrade Task in the Web Console
• Upgrade ERA Agents on managed computers

Before you start

• Linux users: Upgrade ERA 6.4 (and later) for Linux to the latest version.

• If you use an ERA 6.x Proxy component, upgrade your infrastructure with ERA 6.x Proxy.

Prerequisites

Before upgrading to ESMC 7.2, make sure that you have met all ESMC 7.2 installation prerequisites.

Important recommendations before the upgrade

You must have ESET Remote Administrator (ERA) version 6.5 and later to upgrade to ESET Security Management Center 7.2. Check which version of ERA you have installed.

ESMC Server component version 7.2 is not compatible with 32-bit machines (x86 architecture). Upgrading a 32-bit Server machine to 7.2 will fail.

• If you have already run the upgrade and now your system is not working, you need to manually reinstall all ESMC components to the original version.
• If you want to upgrade, you need to migrate your current ESMC to a 64-bit machine, and after successful migration, you can run the upgrade task.

If you have an older unsupported database installed (MySQL 5.5 or MSSQL 2008), upgrade your database to a compatible database version before upgrading the ESMC Server.

Perform a full backup of ERA 6.5:

• Database: Follow these instructions to back up the ERA database.
• Configuration: Copy the Startupconfiguration.ini file, located at: C:\ProgramData\ESET\RemoteAdministrator\Server\EraServerApplicationData
• Certificates: Export the Certification Authorities and Peer Certificates.
• Mobile Device Connector: If this component is used, copy the Startupconfiguration.ini located at: C:\ProgramData\ESET\RemoteAdministrator\MDMCore\EraServerApplicationData\Configuration.

The following steps will upgrade both ERA components (Server, Console) and the ESET Remote Administrator Agent(s) (ERA Agent). When upgrading to the latest version, your policies will be preserved. Update your ERA Server first. Select a few client machines to use as a test for the update and run the task on them (use at least one client from each system/bit category).

Upgrade ERA Server using the Components Upgrade task in the Web Console

Components Upgrade task may take some time to complete

Please be patient during the Components Upgrade task process. It may take some time to complete. Do not restart your ERA Server until the task has completed.

Special characters may cause upgrade to fail

If you have met the requirements for upgrading and your upgrade to the latest version of ESET Security Management Center (ESMC) fails, it could be due to the use of special characters in your ERA password. To resolve this issue, change your ERA password and attempt the upgrade again.

1. Open ESET Remote Administrator Web Console (ERA Web Console) in your web browser and log in.

2. Click Admin  → Client Tasks → ESET Remote Administrator → Remote Administrator Components Upgrade and click New.

1. Click Finish.
2. Create a trigger and add the ERA Server computer as a target to execute the task.
   

   Do not add more target computers

   Add only the computer where ERA Server is installed as a target. Do not add more target computers at this point in the upgrade.

3. Wait a few minutes until all ESMC components installed on the server machine are upgraded. Apache Tomcat service can get turned off during the update. If the Web Console is unavailable after the update, open the services management (run services.msc) and Start the Apache Tomcat service.

4. To verify that your server upgraded to ESET Security Management Center, check Programs and Features in the Control Panel. You will see ESET Security Management Center Server listed as a program if it has been upgraded.

Upgrade ERA Agents on managed computers

When the task is finished on the ESMC Server machine, verify that the ESMC Server works properly. Wait an hour to see if any problems occur. Afterward, you can upgrade Agents on the managed computers using the Components Upgrade task and selecting the static group All as its target. See the step-by-step guide.

If you are running a larger network, with hundreds or more client computers:

ERA 6.x Proxy users

If you have ERA 6.5 Proxy installed, read the respective Knowledgebase articles before upgrading other clients.

• Migrate from ERA Proxy (Windows) to Apache HTTP Proxy in ESMC 7
• Migrate from ERA Proxy (Linux or Virtual Appliance) to Apache HTTP Proxy in ESMC 7

Do not upgrade clients behind Proxy before you set up a suitable proxy solution.

1. 
   
   1. Choose a sample of clients for a test update (include at least one client for each operating system/bit category) and run the task.
   2. We recommend using Apache HTTP Proxy (or any other transparent web proxy with enabled caching) to limit network load. The test client machines will trigger the download/caching of the installers. When the task is run again, the installers will be distributed to client computers directly from the cache.
   3. After a successful test update, proceed with the rest of your clients. Alternatively, target the group to All. The upgrade is not performed on computers that have already been upgraded.

If the Components Upgrade task is not working properly, try upgrading Agents using Run Command Client task.
