# Migration

> Migrate positions between protocols

## Migrating with same base token

Move your USDC lending position from Aave to Compound while keeping the same underlying asset.

**Route mechanics**

* `redeem` existing USDC collateral on AAVE
* `deposit` retreived USDC to Compound `CUSDC` position

```

const fromAddress = "0xd8da6bf26964af9d7eed9e03e53415d37aa96045";
const USDC_ADDRESS = "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48";

const aUsdcAmountIn = parseUnits("5000", 6).toString(); // 5,000 aUSDC to withdraw

const chainId = 1;

const bundle = await client.getBundleData(
  {
    chainId,
    fromAddress,
    routingStrategy: "delegate",
  },
  // Migrate USDC lending position from Aave to Compound

## Migrating to different base position

Switch Aave lending position from USDC collateral to WETH collateral in a single transaction.

Bundle design:

* `redeem` existing USDC collateral on AAVE
* swap USDC to WETH using `route` action
* `deposit` resulting WETH to AAVE (using the `{useOutputOfCallAt: 1}` to reference the swap)
