Koishi Database Migration Plugin

koishi-plugin-migrate-database is a utility plugin for the Koishi chatbot framework, designed to facilitate the migration of data between different database instances. As of version 0.2.1, it provides basic functionality for moving existing Koishi data, which is critical for developers managing evolving bot infrastructures or changing database backends. This plugin is typically released on an as-needed basis to support specific migration scenarios or Koishi core updates. Its primary differentiator is its integration directly into the Koishi ecosystem, allowing for migrations that are aware of Koishi's internal data structures, unlike generic database migration tools. Users should be aware that, as a 0.x.x version, its API and internal workings may still evolve, and thorough testing is recommended before production use.
