# Step 1: Create application backup

php bin/magento maintenance:enable

mysqldump -u [username] -p [database_name] > backup_$(date +%Y%m%d_%H%M%S).sql

# Step 2: Install via Composer with version constraints

composer require netsuite/magento2-extension:^2.1 --no-update

composer update netsuite/magento2-extension

# Step 3: Enable module and run setup

php bin/magento module:enable NetSuite_Analytics NetSuite_Tracking NetSuite_Reports

php bin/magento setup:upgrade --keep-generated

php bin/magento setup:di:compile

php bin/magento setup:static-content:deploy -f

php bin/magento indexer:reindex

php bin/magento cache:flush

# Step 4: Verify installation

php bin/magento module:status NetSuite_Analytics
