Thanks for reading!

Usually your server company should have a ICP platform you that you can manage your ICPs and infos, so if you are using the same server company, the same domain, but different IP with new website, just go to that ICP platform and edit your IP info to the new one, wont cause any problem, wont need to re-verify the ICP, wont get granted. I have consulted our hosting company and that`s their answer. And I checked our ICP platform, there is option to do so as well, should be pretty simple.

Though I am not sure what server company you using but most Chinese ones they have it.

Hope it helps!
