Hilaria,

Our Previous Releases page, https://www.labkey.org/Documentation/wiki-page.view?name=prevReleases, provides access to older releases that you can use to upgrade. You may want to read through the release notes for each intervening version to understand all the changes and caveats.

The Upgrade Support Policy page will be helpful in identifying the next upgrade version, https://www.labkey.org/Documentation/wiki-page.view?name=upgradeSupportPolicy
