今天我把1.7.10的服务端升级到1.8.3，同时也将PlayerSQL插件升级到最新版本。在排除其他插件问题时发现升级PlayerSQL会导致背包数据读取失败（清空背包），再次登录后正常。
手动在Mysql把Data字段的内容替换成原来的内容，发现该问题可以复现。可能是NBT不兼容导致？请问有办法解决么？如果确实由序列化的NBT不兼容导致，可以增加转换数据的功能么？

的确是nbt不兼容，这是大版本数据格式改了的缘故，做转换得不偿失。建议大版本升级前删除掉数据库重新记录数据。

感谢回复。给后来可能遇到的人：
在确保数据全部同步完成后，关闭服务端，升级服务端和插件到1.8.3，然后删除数据库内PlayerData内的数据，重新开服即可。
