Known Issues

• Reports generated in a different language version are not localized after the upgrade.
   
• Reports where the condition "Group by" is used may display duplicated data after the upgrade when receiving new logs.
   
• Replication between different language versions is not fully supported, however, such replication should work once you enable and configure it (Replication to/from a server with a different language version of ERA). Logs may be recorded in different languages in this situation because some of the logs are being received from the server and some from the client.

For more information about upgrading from earlier versions of ESET Remote Administrator to ESET Remote Administrator 5, please see the ESET Remote Administrator Migration Guide.
