# MIMOManagedRebalance :::warning You're reading the legacy **v2** documentation. For current Parallel features, see [v3](/products/parallel-v3). ::: The `MIMOManagedRebalance` action contract handle the super vault empty vault logic described in [Managed Rebalance](/products/parallel-v2/how-it-works/super-vaults-sv/managed-rebalance). ### Process Flow

### Write Methods #### `setManagement(uint256 vaultId, ManagedVault calldata mgtParams)` Sets a vault management parameters. Requirements : * Caller must be the `MIMOProxy` owner the vault or the `MIMOProxy` owner * Selected manager must be whitelisted | Param Name | Type | Description | | ----------- | ------- | -------------------------------------------------------- | | `vaultId` | uint256 | | | mgt`Params` | struct | ManagedVault struct containing all management parameters | **`ManagedVault`** | Param Name | Type | Description | | ------------------ | ------- | ----------------------------------------------------------------------------------------- | | `isManaged` | bool | `true` if vault is under management `false` if not | | `manager` | address | Selected manager address | | `allowedVariation` | uint256 | The maximum allowed slippage on rebalancing swaps | | `minRatio` | uint256 | Minimum vault ratio above which the starting vault be at the end of a rebalance operation | | `fixedFee` | uint256 | Fixed fee paid to the manager | | `varFee` | uint256 | Variable fee paid to the manager | | `mcrBuffer` | uint256 | Rebalancing vault MCR buffer padding | #### `rebalance(uint256 vaultId,` IMIMORebalance.RebalanceData calldata rbData,`IMIMOSwap.SwapData calldata swapData)` Performs a rebalance on a vault by an appointed whitelisted manager on behalf of the vault owner. Requirements : * Contract must be unpaused * Vault must have been created through the user's `MIMOProxy` * Vault must be under management * Caller must be the appointed manager * Rebalance amount cannot be set to zero * Maximum daily operation must have not been reached * Set mint amount cannot be greater than vault debt * The change in vault value due to the rebalance operation must be lower or equal then the `allowedVariation` set by the owner * The final vault ratio must be greater or equal then the `minRatio` set by the owner | Param Name | Type | Description | | ---------- | ------ | ---------------------------------------------------------------- | | `flData` | struct | `FlashLoanData` struct containing flash loan parameters | | `rbData` | struct | `RebalanceData` struct containing rebalance operation parameters | | `swapData` | struct | `SwapData` struct containing aggregator swap parameters | #### `executeOperation(address[] calldata assets, uint256[] calldata amounts, uint256[] calldata premiums, address initiator, bytes calldata params` AAVE `Pool` contract flash loan callback function. Requirements : * Contract must be unpaused * Can only be called by the AAVE `Pool` contract * Flash loan initiator must be the `MIMOProxy`
