Downgrading
Shield API to non-Shield API downgrade
Downgrading from a Shield API version of Workspace Control to a version that does not use the Shield API is not recommended because of security reasons.
An installation of Ivanti Workspace Control that uses the Shield API (i.e. version 10.19.10.0 or higher) cannot be directly downgraded to a version that does not use the Shield API.
If you need to switch to a version with no Shield API, you must first uninstall the Shield API version.
After uninstalling, you can proceed with installing the earlier version that does not use the Shield API.
