7.2.1 Upgrading on Non-clustered Systems

Point

It is recommended that you back up the system before starting the upgrade.
By preparing a backup, in cases when an error occurs during the upgrade, it is possible to return the system to its state prior to the upgrade, simply by recovering (restoring) the system from the backup.

Login to the server on which to perform the tasks. Perform operations after logging in with root (superuser).
Ensure that there is enough available disk space (650 MB in a Solaris environment, 200 MB in a Linux environment) on the server where the upgrade is performed.
In cases when upgrade installation is executed in a state where the capacity required for the upgrade is not available, the following message is displayed and the installation terminates in an error. Re-execute the upgrade after securing the capacity required for the installation.
Output Message (in cases when the directory of the destination of the installation is "/opt"):
```
ERROR:Disk /opt has an insufficient free space. Please execute it again after increasing the disk area.
```
