# Update a pool

Update a pool with the specified name and concurrency limit. You cannot update the default pool. The default pool’s concurrency limit is adjusted to accommodate the new concurrency limit. A pool’s concurrency limit cannot be reduced if it has more running attempts than its new reduced concurrency limit.
