# Update From Previous Versions

If you already have a previously-installed VirtualMetric version, there are several things you have to consider before updating to the current one. See the [Hardware Requirements](https://docs.virtualmetric.com/install-a-virtualmetric-server#hardware-requirements) and [Software Requirements](https://docs.virtualmetric.com/install-a-virtualmetric-server#software-requirements) sections for details.

{% hint style="warning" %}
We recommend that you always keep a proper backup of your *VirtualMetric Database* before performing the update.
