@Angellia Apologies for the delay in response and all the inconvenience caused because of the issue.
Adding to @Andreas Baumgarten point who has correctly pointed out that VM id won't change in this use case.
In your use case only vCPUS, memory and other VM limits will be changed and from backend, VM will be hosted on another datacenter supporting that size
So none of the ID which you have mentioned will change since these are something on Guest level and the mentioned changed are something on Host level so you don't need to worry about that part.
Hope it helps!!!
