GST on sales of used business fixed assets

Hello, We are into hi tech farming business with an setup of greenhouses/polyhouses established in 2017-18 financial year. The greenhouses have been setup as personal files and have not taken any GST input credit and neither GST no as farming is exempted under GST. Since the establishment we have not taken any depreciation and now looking to sell it off at lower price than purchase price, if we sell it off in other state will there be any liability of GST or would we be required to take GST no to sell it to another state.
