The number of oversized packets isn’t that high, so that shouldn’t be the problem. Is it just specific devices that are getting dropped packets or is it across all of them? You may want to try using wireshark to see if it provides more information. You have done a lot of troubleshooting already.
I have also configured a packet capture solution in the network to check what is going on, but there is nothing more than usual. I was looking specifically at layer two, but there are just usual ARPs, DHCP and a few CDPs frames.
Do you think there could be an incompatibility between the old switches and the new ones?
That would be the most difficult troubleshoot step to do in order to narrow the problem down, and I don't even know where to start.
Also, I know the protocols should work, because that's why we have standards for them, but is there any chance that the new switches uses more sophisticated signalling methods that the old ones don't understand?

In that case I am not sure what is causing the drops.

I think the best option is for you to call phone support and see if they have any additional ideas.
