Once this happens, don't worry, there will still be updates and features added to New POS. It's just that the above HAVE to be ready as there is no workaround otherwise. Things like Exchanges and the rest of the Fix a Mistake options, while would be great to have, have workarounds such as returning and rebuying for exchanging, wrong price for missed coupon, and post voiding for wrong payment. (IDK if Exchanges or most of Fix a Mistake is even coming [I hope so.] I know at least Wrong Payment will, but IDK if that's before or after Classic is decommissioned.)
