Some questions about mongodb upgrade
Our mongodb database is a simple one-master-one-slave architecture, currently version 2.4, I want to upgrade to 3.2, the way introduced on the Internet is basically the kind of step-by-step upgrade, I have an upgrade idea, that is, to start a slave database with 3.2, and after the synchronization is completed, directly close the 3.2 slave library and start the master database. I have tested that the data are all there, and I feel that they can be used, but I don't know if there will be any other questions.
