MongoDB3.2如何升級至3.4.6，相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。
MongoDB 升級測試步驟：
1、MongoDB版本升級順序3.2->3.4->3.6->4.0 不能跨版本升級
2、升級到3.4后，您不能降級到3.2.7或更早版本。您只能降級到3.2.8或更高版本
3、先升級所有副本集中的Secondary
4、將Primary節點降級為Secondary節點
5、升級Primary
6、MongoDB3.2升級到3.4，登錄后查看版本信息若還是3.2，執行db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )
7、MongoDB3.4升級到3.6，登錄后查看版本信息若還是3.4，執行db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )
8、MongoDB3.6升級到4.0，登錄后查看版本信息若還是3.6，執行db.adminCommand( { setFeatureCompatibilityVersion: "4.0" } )
###只在升級到4.0執行###
cfg = rs.conf();
cfg.protocolVersion=1;
rs.reconfig(cfg);

通過優先級來修改PRIMARY
