Cisco switches - changing from 1G RJ45 to 10G SFP

Hello

​

We're upgrading from 1G copper RJ45 switches to 10G switches and plan to use SFPs on the switch side. Is there a specific type of copper SFP model we need in order to support our endpoints? We'd like to re-use the existing copper cabling so that we can just move the switch side connections when we come to move the servers from old switch to new switch.

​

Thanks
