Changes to import statements

All imports from @aws-cdk must be changed to aws-cdk-lib

V1: import * as s3 from ‘@aws-cdk/aws-s3’

V2: import * as s3 from ‘aws-cdk-lib/aws-s3’

core types are now at top level

V1: import * as cdk from ‘@aws-cdk/core’

V2: import * as cdk from ‘aws-cdk-lib’;

Construct is moved to constructs package.

V1: cdk.Construct

V2: import { Construct } from ‘constructs’; and use Construct(without cdk.)

Bunch of feature flags in cdk.json are enabled by default and are no more needed. we can remove all those which starts with @aws-cdk/

Finally,

• Delete node_modules and clean install npm install
• redo bootstrap , if new way is not already done at account level. cdk bootstrap
• check the differences cdk diff and deploy cdk deploy
