SOLIDWORKS 2024 as well as SOLIDWORKS 2025 allows you to save files up to two versions back while maintaining the history of operations.

Do you know, what will happen, if you try(a) save e.g. part from SOLIDWORKS 2025 to version 2023, which contains an operation, which was not available in that version?

Below is the answer to this question. We will receive the following message: Incompatible items – cannot be saved in SOLIDWORKS 20xx.

Of course, the operation must be removed first, which was not available in the target version.
