tribe_get_greatest_version_ever_installed( string|object $class )

Gets the highest version number ever installed for the specified class of a plugin having a version_history_slug property or a VERSION constant (i.e. Main classes).

If user initially installed v2, updated to v3, then downgraded to v2, this will return v3. If no historical version records, fallback is the class’ current version. If no version info found, it will return false. Zero may have been logged as a past version but gets ignored.
