Upgrade Unified Console

Brief overview of UC upgrade

Follow the procedure below to upgrade MC.

To upgrade UC with a new version, follow these steps.

Log in as root or a user with sudo privileges on the server where MC is already installed.
Open a terminal window and shut down the MC process:
```
# /etc/init.d/vertica-consoled stop
```
For versions of Red Hat 7/CentOS 7 and above, use:
```
# systemctl stop vertica-consoled
```
Back up MC to preserve configuration metadata.

Important
A full backup is required in order to restore MC to its previous state. Restoring MC is essential if the upgrade fails, or you decide to revert to the previous version of Vertica. For details, see Backing up MC.
Stop the database if MC was installed on an Ubuntu or Debian platform.

Upgrading UC

Download the MC package from the Vertica Website:
```
vertica-console-current-version.Linux-distro)
```
Save the package to a location on the target server, such as /tmp.
On the target server, log in as root or a user with sudo privileges.
Change to the directory where you saved the MC package.
Install MC using your local Linux distribution package management system—rpm, yum, zypper, apt, dpkg. For example:

Red Hat 8
```
# rpm -Uvh vertica-console-current-version.x86_64.rpm
```
Debian and Ubuntu
```
# dpkg -i vertica-console-current-version.deb
```
If you stopped the database before upgrading MC, restart the database.

As the root user, use the following command:
```
/etc/init.d/verticad start
```
For versions of Red Hat 8/CentOS 8 and above, run:
```
# systemctl start verticad
```
Open a browser and enter the URL of the UC installation, one of the following:
- IP address:
```
https://ip-address:uc-port/
```
- Server host name:
```
https://hostname:uc-port/
```
By default, uc-port is 8433.

Stop the UC services.

 sudo ./opt/vconsole/uc/scripts/services.sh stop

Restart the UC services.

 sudo ./opt/vconsole/uc/scripts/services.sh start
