Hi Yanfei, FYI, I ran a quick migration test on our test machines and didn't notice any issues with the v2 patchset. We saw a 10–12% downtime reduction on our setup (100 Gb/s dual-port IB fabric, 100 GB VM, idle load).
As v3 don't change the implementation. Tested-by: Jack Wang <[email protected]> Best regards, Jinpu Wang
