PalletOne has completed the function of automatically upgrading the data in the database with the gptn version upgrading. Once the current data compatible version is stored in database, when the gptn is upgraded, if the data is not compatible with the previous version, the corresponding migration instance can be run according to the version number to update the data to a new version compatible with the current gptn version.

In addition, migration module also supports continuous version upgrading, that is, if there are multiple versions of the current database version and gptn version, migration module will run corresponding migration instances according to its version number to upgrade the database version, thus to realize the upgrading of database version.

The migration module means great help for those staffs like development, testing and maintennance.
