<div>
The version you are upgrading from. It is important to set this config when performing a rolling upgrade to certain versions, as described in the upgrade guide.
You should set this config to the appropriate version before bouncing your instances and upgrading them to the newer version. Once everyone is on the
newer version, you should remove this config and do a second rolling bounce. It is only necessary to set this config and follow the two-bounce upgrade path
when upgrading from below version 2.0, or when upgrading to 2.4+ from any version lower than 2.4.
