New customer installation
Before you upgrade
Migrate LDAP connectors
It is recommended that users remove any ambiguity in their Directory Service Tool connector configurations to allow migration to run as smoothly as possible. This can be by ensuring only one Directory Service Tool connector configuration is set up per domain.
All Directory Service Tool connectors are removed in process of the migration.
How to upgrade
If you are upgrading from a previous version, use the following resources to plan and implement your upgrade.
The SEM Appliance must be upgraded to 2020.2.1 before upgrading to 2020.4.1 See the SEM Upgrade Path to help you plan and execute your upgrade.
Download the upgrade package from the SolarWinds Customer Portal.
In new installations of SEM (6.7 and newer), corresponding agent versions communicate by default using a secure certificate, which no longer supports TLS 1.0, 3DES, or anonymous cipher. If you need to connect to earlier agent versions, navigate to the SEM Console security tab (Settings > Security), and switch the toggle button to enable lower security settings. Versions older than 6.3 are not supported.
Since the release of SEM 2020.4, a password is required to access the CMC command-line interface. The default CMC password is password. See Change the SEM CMC password for instructions on changing it.
File system consistency check (fsck)
During your upgrade, the system may run a fsck check during reboot. This can last 30 or more minutes depending on the quantity of data in the data partition. With the Debian version upgrade, the file system is configured to initiate the check when certain conditions are met:
- 21 mounts since the last check (during the 22nd reboot)
- Six months since the last check
Directory Service Query connectors
The upgrade to 2020.4 and 2020.4.1 automatically replaces Directory Service Query connectors with LDAP configurations. Not connection testing is performed, and therefore it is not guaranteed that resulting LDAP configuration will work. You should check all LDAP configuration after the upgrade.
Raw log files
Raw log file processing is facilitated in the flash-based SEM console only.
Find SEM connector information on Thwack.
For SEM 2020.4 fixed issues see SEM 2020.4 Release Notes.
|Issue: Agents are not able to start due to compromised certificate|
|Cause: Due to a known bug in the RemoteAgentInstallers, auto-upgrade will not work.|
|Workaround: Reinstall agents by running RemoteAgentInstaller 2020.4.1. (Run installation again without executing the uninstall.)|
