Downward compatibility is not allowed from 9 to 7.2  due to data structure changes. Tally has also stopped support for 7.2 now.But if you can use export - import procedure of data provided your entries are not using features which were not in 7.2. If you are not aware of data export import procedure, you can ask ITT students or google it. Its covered in IT training. It wont take more that 10 minutes.
