First, we have provided the upgrade FAQ[1], there are recommended ways there. Then, for your upgrade, I don't know how much time do you take for step 3->5. The potential issue could be, there are two register OAP nodes(one from 6.0 cluster, the other from 6.6). If there is some endpoint register happens, ES lock mechanism is not high performance, so it could make SkyWalking having the performance issue for the production environment. But, from your descriptions, you have finished the processes, then you don't need to worry about the concern. I write those for you just for a reminder in case you will upgrade again in the future.
