Not difficult at all, and when locking you in to a 3 year contract with the minimum core count set for that 3 years being what you have when april starts.
We are expecting around 8x increase in costs, so we are cutting esxi host core counts to a minimum, buying cpus and swapping them out. Our parent company has around 150000 cores running esxi.
The section I'm in has far less than that, so will find doing that easier.
We will be at the same cost, hopefully, as we were before the price increase, evaluating alternatives and moving off over the next year (being stuck on a 3yr contract).
We still haven't received all the terms for the licensing, if disabling cores is OK (why we are buying cpus), it has been only verbally stated, no, you can't disable cores to reduce the core count for pricing, disabled cores still count.
We haven't received how different add ons will be billed.
Discounts are still being negotiated, with overage (above agreed min core count) so far set at 100% no discount.
It's a shit show.
