This section guides you through the upgrade from your current SDK implementation to our latest CSQ SDK.

Upgrading has no impact on your current data collection (except for "Heap Classic SDK") and does not alter the data observed on the platform.

It mainly consists of searching and replacing APIs according to the mappings provided in the upgrade guides.

Get started by selecting the upgrade guide that corresponds to your current implementation:

* **[Heap Core SDK](../upgrade-from-heap-core-sdk/)** - Upgrade from Heap Core SDK
* **[Heap Classic SDK](../upgrade-from-heap-classic-sdk/)** - Upgrade from Heap Classic SDK
* **[Heap SDK + Contentsquare SDK](../upgrade-from-heap-and-cs-sdk/)** - Upgrade from combined Heap and Contentsquare SDKs
