Translation Hub deprecation: Can existing custom models be used through Cloud Translation API v3?

We currently use Translation Hub with several custom translation models and glossaries.

With Translation Hub retiring in September 2026, can existing custom models and glossaries continue to be used via the Cloud Translation API v3 (Advanced)?

If yes, are any migration steps required, or can the existing models be called directly through the API?

Any guidance or migration documentation would be greatly appreciated.
