# NOTES for updating new versions

If it is necessary to update old versions such as v1.3.84, v1.3.70, v1.3.65 or even lower to the new version v2.561

&#x20;  **Users using MySQL need to export playerinv's database as an SQL file for backup!!**

&#x20;  **Users using SQLite (i.e. not using MySQL) should backup the Databases.db file in the plugin's    configuration folder!!**

&#x20;  **When installing a new version, make a backup of the settings in the original config.yml and delete all files except for the database files**

&#x20;  **To ensure that complete and correct configuration files are generated during the installation of new versions**

&#x20;  **After generating the configuration file, reset the original config.yml based on the new file and restart the server to take effect**

&#x20;  **When installing a new version and starting the server, the plugin will determine whether the old version storage table is included for data migration operations**

&#x20;  **The data migration operation requires a waiting time of several seconds, which depends on the amount of data**

&#x20;  **After the data migration is completed, the old storage table name will be changed to InvData\_backup to ensure that the migration is completed and only performed once**

At this point, the plugin has successfully completed the upgrade from version v1.0 to version v2.5!
