# Upgrading

In this section, you will find recipes to upgrade from the OmniSci to the HEAVY.AI platform and upgrade between versions of the HEAVY.AI platform.

### Supported Upgrade Path

The following table shows the steps needed to move from one version to a later one.

<table><thead><tr><th width="150">Initial Version</th><th width="150">Final Version</th><th>Upgrade Steps</th></tr></thead><tbody><tr><td>OmniSci less than 5.5</td><td>HEAVY.AI 7.0</td><td>Upgrade to 5.5 --> <a href="upgrading-omnisci/upgrading-omnisci-1">6.0</a> --> 7.0</td></tr><tr><td>OmniSci 5.5 - 5.10</td><td>HEAVY.AI 7.0</td><td>Upgrade to <a href="upgrading-omnisci/upgrading-omnisci-1">6.0</a> --> 7.0</td></tr><tr><td>HEAVY.AI 6.0</td><td>HEAVY.AI 7.0</td><td>Upgrade to 7.0</td></tr></tbody></table>

{% hint style="info" %}
Versions 5.x and 6.0.0 are no longer supported; use these only as needed to facilitate an upgrade to a supported version.
{% endhint %}

Example: if you are running an OmniSci version older than 5.5, you must first upgrade to 5.5, then upgrade to 6.0 and after that upgrade to 7.0. If you are running 6.0 - 6.4, you can upgrade directly to 7.0 in a single step.
