Cat 6 Cable

If you had to extend existing cables how would that be done? Can you even splice or terminate it somehow and extend it?

Not recommended. Better to pull new.

You can use two RJ45 connectors and a coupler. Depending on what data speed is needed through the cable that might be adequate. They also make punch down blocks to splice two cables together.

As Tom said, pulling a clean home run is the best solution. If that isn't an option, then properly terminate the end that needs extended (my preference would be with a keystone), and run the additional length (again with proper terminations, keystones in my world, at each end), using a short patch cable in the middle. You'll end up with:
Original end - original wire - new keystone - patch cable - new keystone - new wire - new keystone at the final location.
Keep in mind that the key-patch-key will make your effective run longer than it would seem, and 328ft can creep up on you really fast.

RJ45 and couplers can work, but we've found them to be somewhat unreliable, especially when bent near the connector. Just last month I had to cut off and re-terminate several new CRAC links because the vendor used stranded IDC connectors on solid CAT6. Punch-downs are a non-starter unless this is telephone/T1 level stuff.

To relocate a network closet or server rack I use a cat 6 110 punch down block, like this Leviton one

Cat 6 110-Style Wiring Block Kit, includes 96-pair block with legs, la

Leviton Cat 6 110-Style Wiring Blocks provide a centralized location to easily terminate 22-26 gauge solid copper wire for telephone, voice, and data applications. The wall-mount and rack-mount blocks exceed Category 6 channel requirements. For more information please visit www.leviton.com

If its one or two cables I would as others suggested pull a new run.
Rather than have the customer specify the copper cable type its better to specify the network design speed, for most offices its a 1000BASE-T.
