MongoDB3.2 how to upgrade to 3.4.6, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.
MongoDB upgrade test steps:
1. MongoDB version upgrade sequence 3.2-> 3.4-> 3.6-> 4.0 cannot be upgraded across versions.
2. After upgrading to 3.4, you cannot downgrade to 3.2.7 or earlier. You can only be downgraded to 3.2.8 or later
3. Upgrade the Secondary in all replica sets first
4. Downgrade Primary node to Secondary node
5. Upgrade Primary
6. MongoDB3.2 is upgraded to 3.4.If the version information is still 3.2after login, execute db.adminCommand ({setFeatureCompatibilityVersion: "3.4"}).
7. MongoDB3.4 is upgraded to 3.6.If the version information is still 3.4after login, execute db.adminCommand ({setFeatureCompatibilityVersion: "3.6"})
8. MongoDB3.6 is upgraded to 4.0. if the version information is still 3.6after logging in, execute db.adminCommand ({setFeatureCompatibilityVersion: "4.0"})
# only perform # when upgrading to 4.0
Cfg = rs.conf ()
Cfg.protocolVersion=1
Rs.reconfig (cfg)

Upgrade Primary to 3.4.6
There are two ways to demote a Primary node to a Secondary node, one is rs.stepDown (), and the other is to modify the Primary by changing the priority
Shard1:PRIMARY > rs.stepDown ()
Or
Modify PRIMARY by priority
Shard1:PRIMARY > config=rs.conf () / / View the current configuration and store it in the config variable
Shard1:PRIMARY > config.members [0] .priority = 50 / / modify the config variable. The priority of the first group member is 50.
Shard1:PRIMARY > rs.reconfig (config) / / configuration takes effect
