Good Morning,
I have 2 sites that we are going to merge into 1. I am not to concerned about IP Scheme as neither site has over lapping addresses.
Site 1 10.32.24.0/21
Site 2 10.32.32.0/21
My concern is Vlans, both sites use the same vlan numbers and VTP. How can merge the 2 site and manage the VLAN?
Vlan examples
Site 1 Vlan:
interface Vlan601
ip address 10.32.24.1 255.255.254.0
interface Vlan645
ip address 10.32.28.1 255.255.255.192
interface Vlan646
ip address 10.32.29.1 255.255.255.0
Site 2 Vlan:
interface Vlan601
ip address 10.32.32.1 255.255.254.0
interface Vlan646
ip address 10.32.36.1 255.255.254.0
interface Vlan678
ip address 10.32.38.1 255.255.255.128
Thanks

If you want to use the same vlan numbers then you need to route the vlans on different L3 devices and route between those devices because you won't be able to create the same L3 interface twice on the same device.

Yeah
"merge" might have been a bad term.
Objective:
Site 1 is the main warehouse, Firewall, Layer 3 & 2 switches ISP is 50 mb circuit
Site 2 is the secondary warehouse Firewall, Layer 3 & 2 switches ISP a 4g modem
The goal was for site 2 to share the ISP of site 1 leveraging a point to point wireless bridge. The building are 200 yards apart with no obstructions.
thanks

If each site has a L3 switch just make a routed link across the wireless and use a default route in site 2 pointing to site 1 for internet connectivity.
You may also want to run a routing protocol for each sites subnets or you could just use statics.

So site 2 has 2960s, not a true layer device.
I will try the routed interfaces first and see how it works.
