Customer can apply for instance refresh or cloning, but whether there is a limited times for instance refresh?
BIzX, ONB and LMS
Customers can request 12 refreshes at no cost.
They can request more - but there may be a fee after 12 is reached.
Also - keep in mind that BIzX, ONB and LMS are requested separately.
So if customer has BizX, ONB and LMS, and they want to refresh all at the same time, then that would count as 3 of the refreshes out of the 12.
