After Active-Passive solace brokers has switched there role. what is the best way to do switchback

auto-revert is an appliance only feature that doesn’t apply to software brokers. In any event, I’d recommend you don’t use it, as it can cause “flip-flops” when the primary is unstable. You should also stay running on the backup until you’ve identified why the primary has failed, as until you understand that, you have no guarantee that the problem will not recur.
