I would assume that since you want to convert from CQ to CBWFQ as
accurately as possible, consider the following:
1. CQ assumes 100% of the bandwidth. It doesn't matter whether you
have 1 queue or 10 queues it's always moving from queue to queue (even
though it only takes effect during times of congestion.)
2. By default an interface won't let you reserve more than 75% of its
bandwidth with CBWFQ.
Since you want to be accurate use the max-reserve-bandwidth 100
command. This way you are actually distributing bandwidth like the CQ
specifies, not 75% of what the CQ specifies.

Do we need to consider the default bandwidth for CQ and CBWFQ
