Clarification Required on Redwood Helper Tool Auto Complete Rule Migration

Summary:

Hi Team,

We are attempting to migrate our Auto Complete Rules using the Redwood Helper Tool. However, every rule is marked as "Not Migratable" with the message:
"Rule cannot be fully migrated because it contains unsupported artifacts."

We need clarification on the following:
1.    Why are all of our Auto Complete Rules identified as containing unsupported artifacts?
2.    What specific artifacts are considered unsupported, and how can they be resolved?
3.    If the Redwood Helper Tool is unable to migrate these rules, what is the recommended migration approach?
4.    What is the intended purpose of the Redwood Helper Tool if Auto Complete Rules are consistently reported as non-migratable?
