# Collibra Platform Self-Hosted

Collibra Platform Self-Hosted (CPSH) is a Collibra solution that allows you to install Collibra Platform Self-Hosted on an infrastructure of your choice. This solution allows you to continue using CPSH in an on-premises environment. Compared to our previous on-premises offering, Collibra Data Governance Center 5.9.1 and older, new features that were previously only available in our cloud offering, are added, though there are still differences between these offerings. For a full overview of available features, go to the [feature availability page](https://productresources.collibra.com/docs/cpsh/latest/Content/ReleaseNotes/ref_feature-availability.htm).

{% hint style="info" %}
If you are using Data Quality & Observability Classic on-premises, we recommend you upgrade to at least the 2023.09 release. There are several key fixes in that version which make your upgrade much more seamless.
