Upgrade MongoDB Version and FCV
You can upgrade the major, minor, or feature compatibility versions of your MongoDB resource. Configure these settings in your MongoDB Database Resource Specification.
Overview
To upgrade your resource's major or minor versions, set the
spec.version setting to the desired MongoDB version.
To modify your resource's
feature compatibility version,
set the spec.featureCompatibilityVersion setting to the desired
version.
Note
If you update spec.version to a later version, consider setting
spec.featureCompatibilityVersion to the current working
MongoDB version to give yourself the option to downgrade if
necessary. To learn more about feature compatibility, see
setFeatureCompatibilityVersion in the MongoDB Server
Documentation.
Procedure
To upgrade the standalone deployment's MongoDB version from 4.2.2-ent
to 4.4.18-ent, complete the steps in the following syntactic example.
If you update spec.version to a later version without setting the
spec.featureCompatibilityVersion to any value, the Feature
Compatibility Version (FCV) upgrades to the same version that you specify
in spec.version. However, you can explicitly specify a previous
version for the FCV. The following example illustrates this use case.
It sets spec.version to 4.4.18-ent and
spec.featureCompatibilityVersion to 4.2.
