MongoDB3.2如何升级至3.4.6，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
MongoDB 升级测试步骤：
1、MongoDB版本升级顺序3.2->3.4->3.6->4.0 不能跨版本升级
2、升级到3.4后，您不能降级到3.2.7或更早版本。您只能降级到3.2.8或更高版本
3、先升级所有副本集中的Secondary
4、将Primary节点降级为Secondary节点
5、升级Primary
6、MongoDB3.2升级到3.4，登录后查看版本信息若还是3.2，执行db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )
7、MongoDB3.4升级到3.6，登录后查看版本信息若还是3.4，执行db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )
8、MongoDB3.6升级到4.0，登录后查看版本信息若还是3.6，执行db.adminCommand( { setFeatureCompatibilityVersion: "4.0" } )
###只在升级到4.0执行###
cfg = rs.conf();
cfg.protocolVersion=1;
rs.reconfig(cfg);

通过优先级来修改PRIMARY
