Changes in the node configuration file¶
This section provides information to help you identify changes in the configuration file depending on the node version.

Changes in the node configuration file of the 1.4.0 version¶
The database for storing the state inside the node has changed, now RockDB is used instead of LevelDB. If you upgrade to release 1.4.0, you can’t roll back. Database migration occurs automatically when switching to release 1.4.0 and may take a long time. If you have several nodes in the network, then the nodes must be updated strictly sequentially! It is recommended to make a backup copy of the old database.
