Plz follow these steps for easy setup.
Switch-1

If the existing switch is VTP server, configure the new switch to be a VTP client.
Configure the VTP domain on the new switch. If you are using a VTP password, configure that on the new switch.
Configure the uplink for trunk if needed.

Hi Lewis,
In order to extend a VLAN to another switch, you will need to configure VLAN Trunking on both sides for the link between the switches.
I would recommend you to go through the following documentations which will give you detailed explanation and examples to achieve this.
Configuring 802.1Q Trunking Between a Catalyst 3550/3560/3750 and Catalyst Switches That Run Cisco IOS Software

Hi Lewis,
Inorder to transfer / pass one vlan in one switch to another switch you need to use VTP technology.
