# 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="/installation-and-configuration/installation/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="/installation-and-configuration/installation/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>

<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.
</Info>

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.
