Start with the risk, not the contract
Changing Drupal agencies is an operational decision. The safest path is to understand code, access, hosting, deployment and backlog risk before anyone promises a clean takeover.
Signals that your Drupal agency may no longer fit
These are the patterns that usually justify a second opinion or a controlled vendor-change process.
The handover checklist buyers should prepare
You do not need a perfect handover package, but you need enough access and context to let a senior Drupal team audit the platform responsibly.
A practical first 30 days
The first month should reduce uncertainty. It should not become another open-ended discovery phase.
Use the guide to prepare. Use the audit to decide.
A vendor switch should not depend on a sales promise. Start with a paid Drupal audit when you need an independent baseline, a risk register and a practical roadmap before moving the platform to a new long-term owner.

Vendor change is a scenario. The service you buy first is the audit; the long-term model is support, development or team extension.
