Migration from version 1.4 to 2.0

Breaking changes
Important We have decided to separate our project to several packages as it's now getting bigger and the need of separation of concerns would become inevitable. Listed below are all the required steps we would like you to guide you through. Please note that all the steps are being made from the root folder of your project and are processed in due course.
We strongly recommend that you do global uninstall of aeproject with npm uninstall -g aeproject and reinstall the newer version - npm install -g aeproject
Delete your node_modules folder, so that you do not keep the deprecated module in your project.
Delete your old dependency to aeproject in the package.json file.
Do npm install
Now that you have aeproject globally, run aeproject init --update in your root directory. This will incorporate aeproject-lib to your existing project
Everywhere you have require('aeproject').Deployer; now should be amended to require('aeproject-lib').Deployer. 
Deploying in v1.4
Example:
const Deployer = require('aeproject').Deployer;
​
const deploy = async (network, privateKey, compiler) => {
    let deployer = new Deployer(network, privateKey, compiler)
​
    await deployer.deploy("./contracts/ExampleContract.aes")
};
​
module.exports = {
    deploy
};
Deploying in v2.0
Here in v2.0 the Deployer is exposed through aeproject-lib
const Deployer = require('aeproject-lib').Deployer;
​
const deploy = async (network, privateKey, compiler) => {
    let deployer = new Deployer(network, privateKey, compiler)
​
    await deployer.deploy("./contracts/ExampleContract.aes")
};
​
module.exports = {
    deploy
};
Testing smart contract v1.2
const Ae = require('@aeternity/aepp-sdk').Universal;
​
const config = {
    host: "http://localhost:3001/",
    internalHost: "http://localhost:3001/internal/",
    gas: 200000,
    ttl: 55,
    compilerUrl: 'https://localhost:3080'
}
​
describe('Example Contract', () => {
​
    let owner;
    let options = {
        ttl: config.ttl
    }
​
    before(async () => {
        const ownerKeyPair = wallets[0];
        owner = await Ae({
            url: config.host,
            internalUrl: config.internalHost,
            keypair: ownerKeyPair,
            nativeMode: true,
            networkId: 'ae_devnet',
            compilerUrl: config.compilerUrl
        });
​
    })
​
    it('Deploying Example Contract', async () => {
        let contractSource = utils.readFileRelative('./contracts/ExampleContract.aes', "utf-8"); // Read the aes file
​
        const compiledContract = await owner.contractCompile(contractSource, { // Compile it
        })
        // Deploy it
        // [] - empty init state object
        const deployPromise = compiledContract.deploy([], options);
​
        await assert.isFulfilled(deployPromise, 'Could not deploy the ExampleContract Smart Contract'); // Check it is deployed
    })
​
})
Testing smart contract v2.0
Now the test file is completely reworked.
const Deployer = require('aeproject-lib').Deployer;
const EXAMPLE_CONTRACT_PATH = "./contracts/ExampleContract.aes";
​
describe('Example Contract', () => {
​
    let deployer;
    let ownerKeyPair = wallets[0];
​
    before(async () => {
        deployer = new Deployer('local', ownerKeyPair.secretKey)
    })
​
    it('Deploying Example Contract', async () => {
        const deployPromise = deployer.deploy(EXAMPLE_CONTRACT_PATH) // Deploy it
​
        await assert.isFulfilled(deployPromise, 'Could not deploy the ExampleContract Smart Contract'); // Check whether it's deployed
    })
})
