BTW, such a conversion might be a good time to review your 6500 QoS to take advantage of 9k QoS features.  Also possible the 9k might not support some 6500 QoS features.

The QoS configurations from an older IOS (15.1) on a Catalyst 6513 can generally be translated to a newer switch like the Catalyst 9410 R. However, exact commands might differ between the IOS versions and the switch models. You'll need to review the specific QoS configuration details for the new switch model and adjust accordingly.
