After creating a vault, the admin can update several configuration parameters such as fees, cap, withdrawal settings, and manager authority.
What Can Be Updated
Update Via UI

Update Via SDK
The v2 SDK uses getUpdateVaultConfigInstructionAsync, one field at a time.
Update A u64 Field
Update A Fee Field
Management Fee Special Case
For ManagerManagementFee and AdminManagementFee, append the vault LP mint account to the final instruction accounts:
The maintained admin-update-vault-config.ts scripts show the exact extra-account pattern used in production.
Update Manager
Manager and pending-admin changes use a 32-byte encoded address as the payload.
Serialization Reference
Be careful when changing manager authority. Once moved, the old manager key can no longer operate the vault.
