Recommended action to migrate TTL index?

[auspham]

Hi there,

I'm following this script to convert from RU to vcore. However, during migration I got into this problem here:

    raise ValueError(f"Cannot migrate TTL index on _ts field for collection {collection_name}.")
ValueError: Cannot migrate TTL index on _ts field for collection test_plans_history.

I have a few questions as below:

1. What's the recommended action to migrate these TTL fields?
2. The script was stopped because of this. Should we allow it to continue to migrate as much as possible and skip the failure ones?
