We need to use the Event filtering feature of TiCDC, but this feature is only available in v6.2. The company is using an older version of TiCDC. Is there a way to use the Event filtering feature without upgrading the old version of TiCDC? Currently, I’m wondering if TiDB can support using different versions of TiCDC simultaneously.

Older versions cannot directly support new features. Unless you upgrade the major version of TiDB…

TiDB is compatible according to major version numbers. If you were previously using 5.X, you can use the latest 5.X version of tiCDC.
Refer to the compatibility instructions below:

The first version is always the one that adapts to new features, while backward compatibility is maintained for basic functions.
