# 版本升级方法
> JeecgBoot属于平台级产品每次升级改动较大目前做不到平滑升级。
### 增量升级方案
#### 1.代码合并
本地通过svn或git做好主干在分支上做业务开发jeecg每次版本发布可以手工覆盖主干的代码对比合并代码
#### 2.数据库升级
- 从3.6.2+版本增加flyway自动升级数据库机制支持 mysql5.7、mysql8;
- 其他库请手工执行SQL, 目录: `jeecg-module-system\jeecg-system-start\src\main\resources\flyway\sql\mysql`
> 注意: 升级sql只提供mysql版本如果有权限升级, 还需要手工角色授权,退出重新登录才好使。
#### 3.兼容问题
每次发版,会针对不兼容地方重点说明。
