Backwards Compatibility: Ansys 2025 R1 was tested to read and resume databases from the following previous versions: 2023 R1, 2023 R2, 2024 R1, and 2024 R2. Note that some products are able to read and resume databases from releases prior to 2022 R2. See the specific product sections below for more information. For those products that cannot directly read an earlier database in 2025 R1, first resume it in a supported version and then resume that database in 2025 R1.

Upward/Forward Compatibility: No previous release has the ability to read and resume a database from a more recent release.
