I have worked as a mechanic for years and have had extensive training when it comes to different types of oils and how they will interact when mixed. I am not expert by any means, but I have done research on the subject, and I do have hands-on experience with the subject.
I know you can switch at any time if you want to; however, it is not recommended to go directly from full synthetic to conventional. To do so you must properly flush and clean the engine. Not all, but many synthetic oils will coagulate when mixed with pure conventional oil. Synthetic blended oils are not simply conventional and synthetic mixed as many think. Synthetic blend (also known as half synthetic) has a conventional oil base, but the manufacturers add a variety of detergents and other additives to the conventional oil to give you "the best of both worlds". Depending on application and climate some may benefit from running conventional oil over synthetic, though in most modern automotive engines people will benefit from full synthetic under the right conditions.
I did not elaborate more in my above posts as I wanted to keep it simple. A general rule of thumb for internal combustion engines is that you do not go back to conventional oil after you have made the switch to full synthetic.
Going from full synthetic to synthetic blend is in most cases ’okay’ without a proper flush, but since the OP had full synthetic in the engine before the previous oil change
