# Deprecation of ZCQL API Version v1

As of **August 2023**, Catalyst has [released](https://docs.catalyst.zoho.com/en/release-notes/all/#2023---august) the **ZCQL API Version** `v2` also known as **ZCQL parser** `v2` and announced the deprecation date of ZCQL API Version `v1` on **February 29, 2024**. 

![Data Store- Schema View](https://docs.catalyst.zoho.com/images/announcements/zcql_announcement_console.webp)

Considering that some of our users have not migrated their codebase from `v1` to `v2`, Catalyst had extended the deprecation date by a month to March 31, 2024. We have now further extended the deprecation. The support for ZCQL parser `v1` will be terminated on **April 30, 2024**. We urge our users to migrate your codebases that employ `v1` to `v2` before this date.

To migrate your ZCQL queries to `v2` from `v1`, you need to apply the upgrades syntax to your queries and validate them. To learn about the syntax upgrades and improvements on **ZCQL API Version** `v2`, visit this [help documentation](https://docs.catalyst.zoho.com/en/cloud-scale/help/zcql/syntax-exceptions/).
