An implementation engineer needs to perform an upgrade of IdentitylQ between releases.

When upgrading SailPoint IdentityIQ between releases, it is not necessary to install every version in sequential order between the current version and the target version. SailPoint provides upgrade paths that often allow skipping several major versions by directly upgrading to the desired target version from a supported previous version. However, it is crucial to follow the specific upgrade paths and procedures documented by SailPoint, which may involve intermediate steps or specific considerations depending on the versions involved.

Therefore, the correct answer is B. No.
