How do I complete a full product sync manually in Magento 1.X?

• Visit Tagalys configuration in your Magento admin panel

• Goto Support & Troubleshooting

• Click on the "Trigger Full Product resync now"

• If CRON is enabled, the full product resync will start automatically the next time the cron runs. 
• If CRON is not enabled, the manual sync button needs to triggered using the Manual Sync trigger.
