# バージョン確認
cdk --version

cdk migrate --stack-name {ターゲットのスタック名} --language {CDKの言語} --from-stack

cdk migrate --stack-name cdk-migrate-test --language typescript --from-stack

cdk migrate --stack-name cdk-migrate-test --language typescript --from-stack

This is an experimental feature. We make no guarantees about the outcome or stability of the functionality.
 ⏳  Generating CDK app for cdk-migrate-test...
Applying project template app for typescript
Initializing a new git repository...
Executing npm install...
✅ All done!
