Data Directory and Compatibility

Data Directory

• Compatibility: The blockchain and wallet files in the data directory are generally compatible between versions. Therefore, there is typically no need to alter the data directory when upgrading.
• Automatic Upgrades: Occasionally, the format of these files changes. The new version of Cyberyen Core includes code to automatically upgrade the files to the new format, eliminating the need for manual intervention.

Special Cases

• Upgrading from Very Old Versions: Sometimes, upgrading blockchain data files from very old versions to the new version is not supported. In such cases, it might be necessary to re-download the entire blockchain. Always check the release notes of the new version if you plan to upgrade from a very old version.
• Downgrading: Downgrading to an older version may not be possible due to changes in data file formats. Again, refer to the release notes for guidance if you are considering downgrading.
