I currently have 2 6500 running on sup2/msfc2 hardware platforms. Since the sup2/msfc2 is end of life, my goal is to replace both 6500 with a 3560, 3750 or something else.
The 6500's have about 12 uplinks sfp connections, the 3750 only has four.
How could I get this done?
What aspects should I be considering while designing this?
A snapshot is attached.

There is a 3750 w/12 port SFP.

When designing make sure you know and understand your traffic flows. Then match products to your networks needs and growth pattern.
Hope that helps.

Thanks for your help Collin.

As Collin notes, there is a 12 SFP port 3750. Or you use three coppper 3750s that have 4 SFP ports. Or you can mix both in the same stack.
What you might consider, a 3750 is not a 6500. Lots less features and/or capabilities. Except for a very small network, I would be concerned about using it as a core. Perhaps a better choice if you want to use a stackable, would be the 3750-E.
Another possible option for you might be upgrade your sup2 to a sup32 variant. Good chance you'll be able to retain your line cards but you might need a fan upgrade and/or power upgrade.

Joe,
I didn't get quitte well what you meant by "use three copper 3750s that have 4 SFP ports. Or you can mix both in the same stack."
Thanks for your support and input.

Many of the 24/48 Ethernet (copper) port 3750s have 2 or 4 SFP ports. E.g. "Catalyst 3750 - 48TS 48 Ethernet 10/100 ports and 4 SFP ports". When you stack 3750s you make one logical device. So, if you stacked three 3750s and each had 4 SFP ports, you would have a logical switch with 12 SFP ports. This then should be able to take the place of the 12 SFP ports your 6500 has now.
Or, since you can mix 3750 models in the same stack (virtual device) a 3750 with 48 Ethernet (copper) ports and 4 SFP ports combined with the 3750G-12S which provides only 12 SFP ports would make for a logical device with 48 Ethernet (copper) ports and 16 SFP ports.
Building a multi-member 3750 stack is much like adding line cards to a chassis, except there is no chassis, but still only one logical device.
