# UCMDB Tip: How to update the agent configuration without upgrading the agent ?

In Universal CMDB (UCMDB) ver.10.20 there is a new feature, when using Management Zones. There is an option called "Upgrade Agent", which should only update the agent configuration. How does that option work?

In order to update the agent configuration without upgrading the agent binary, it is necessary to enable the option "Update UD Agent" and disable the option "Upgrade UD Agent".

The option "Update UD Agent" technically means "Update UD Agent configuration", previously (before UCMDB ver.10.20), the "Update UD Agent" option had two functions merged together - to update agent configuration and to upgrade the agent binary and it worked as follows:

- if the Agent was the same on the target device, then only the Agent configuration was updated
- if the Agent was different, then the Agent was upgraded
- if that option was disabled, then nothing happened

In UCMDB ver.10.20 the option was split in two, and "Update UD Agent" part is supposed to update the configuration, while "Upgrade UD Agent" will do the upgrade of the agent binary (if selected). Therefore, in order to do agent upgrade and change the configuration, it is necessary to select both options, but in order to only update the configuration without upgrading the agent binary, one needs to select the option "Update UD Agent".
