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.

Upgrade Paths supported

It's not always possible to upgrade from your actual product version to the last one, but one or more intermediate upgrade steps are needed.

The following table shows the steps needed to move from one software version to another.

Initial versionFinal versionUpgrade Steps

OmniSci less then 5.5


Upgrade to 5.5 --> 6.0 --> 7.0

OmniSci 5.5-5.10


Upgrade to 6.0 --> 7.0

HEAVY.AI 6.0-6.4


Upgrade to 7.0

Versions 5.x and 6.0.0 are not currently supported; use these only as needed to facilitate an upgrade to a supported version.

As an example, if you are using an OmniSci version older than 5.5, you must upgrade to 5.5, then to 6.0 and after that to 7.0, while if you are using 6.0-6.4.4 you can upgrade to 7.0.0 in a single step.
