Notes before upgrading/downgrading

Note: Skip this section if you are deploying LUNA PLATFORM from scratch.

During an update/downgrade, you must perform the following steps:

• Plan the impact on running services that use databases. See the "Recommendations services behavior during environment preparation" section of the Storages utility manual for details.

• When downgrading, specify the desired version of LUNA PLATFORM in the --platform-version variable in the following files:

• storages/overlays/check/overlay-check.yaml

• storages/overlays/prepare/overlay-prepare.yaml

See "Prepare environment".

• Uninstall old Helm charts and environment preparation manifests before installing new ones. See "Uninstall old Helm charts and manifests".
