I am trying to update my mongo sharded version from 2.4 to 2.6.3.
I have some queries on steps to update this.
- When I will run one mongos with the
--upgradeoption, will it update all the config and mongos or do I have to manually replace binaries on each one of them and restart the mongos and config?
- How can I update my config servers without downtime?
- Upgrading shard needs to down its members one by one and update the binary. Is there any other way to do it?
