HI Kumar, [PLS RATE if HELPS]

In Cisco you have a concept of VTP. Where you can create a VTP Domain with Server and Clients (includes transparent modes).

In Server mode (create, delete and modify vlan info)

In client mode (cannot create, delete, etc., vlan info)

In Transparent mode (do not participate in VTP)

Connect both the Switches via an UP-link where ports configured as Trunk.

The Primary Switch can be configured in VTP Server mode with all VLAN and Domain Information stored. The second switch can be configured as VTP client mode as a part of VTP Server domain. So, once both the Switches are in same domain the VTP will carry VLAN Information based on config revision number.

Hi,

You need to connect the 2 switches via a trunk link, and as for the VLAN information you can either use VTP to update VLAN info between the 2 switches, by adding both switches to the same VTP domain (one of them as a server and the other as a client or both are servers), or make both transparent and do the VLAN info manually on both.
