There is no obvious way to estimate this largely due to several mitigating factors.  Regards,  Rich
Just got through a DR exercise and was curious to track the amount of time it takes a CG to get caught up after putting several of them into direct access mode on the destination side.  Trying to give mgmt a sense of that timing but am unsure where I can pull the exact amount of time it took for the partial sweep to complete.
