I have an E4s_v3 box that we want to beef up to do some load testing. I need more RAM and CPU. What is the biggest box I can upgrade to and then subsequently downgrade back to? We only need a week of the bigger box to run some metrics. I am worried that I upgrade to a box that I can’t then downgrade easily. The E4s_v3 has 32GB of RAM and 4 vcpus. Ideally I want to get upwards of 256GM of RAM and 32 vcpus to load test to match the production server.
