1. It has single controller so is it required cluster switch ?
2. Cabling need to be change? We have NetApp DS4243 Disk shelf and single controller
3. We can directly upgrade from 8.1.4 7 mode to 8.3.3 cluster mode?
4. If I upgrade to cluster on tap OS from 7 mode all data in volumes erase?
Please guide me.
