# Virtual Appliance

### Upgrading VA 48.x to later versions

• Make sure the upgrade occurs during a maintenance window. The upgrade may take up to an hour and requires a reboot of your system(s).

• Make sure that the size of the root partition is 64 GB or higher. For information on increasing the partition size, see Increase the Size of the Partition.

• Make sure there's at least 16 GB of free space on the /opt/ns/upgrades partition where the upgrade pkg is downloaded.

• The log partition, /var/ns/docker/mounts/lclw/mountpoint must have at least 20 GB of free space.

• Ensure that the urldbz package is installed on a DPoP appliance. You can verify this by running, the show version-info command. For instructions to install the urldbz package, see Upgrade the additional Appliance Packages.

Use the df command to check the available space on the upgrade and log partitions. If the output of the command shows high disk utilization, then you can delete the older version of the appliance by running the following command.

upgrade software delete version <version number>
