Stock transfer - Goods and Services Tax - GST

I have 4 factories situated in different states i.e. UP, Bihar, Telengana, and Rajasthan and is in manufacturing of exempted goods. I have a central warehouse situated in UP. The raw materials I prorcure for manufacturing of exempted goods are taxable. Usually, I directly supply the goods to the customers from my factories. At times, due to demand from one specific region, I shift the goods from factories to the central warehouse. What will the implications on the ITC under gst law? Can I save the ITC on the stock transfer to central warehouse
