Hi Team,
I have created the DHCP pool on L3 switch, Now i want to use windows server as DHCP server.
What are the changes I have do on L3 switch. I have already created the DHCP scope on windows server, also I have mulitple VLAN so also need help with DHCP relay

First check from switch are you able to reach DHCP Server and from DHCP Server to switch
then on the Layer3 SVI Interface add
interface vlan X
ip helper-address x.x.x.x
and connect end device to van X port and test is the DHCP IP allocated, and check on the DHCP Server address leases
Once that is confirmed remove the Scope from Layer3 switch and migrate rest of the subnet same way.

Do I need to add the DHCP server address as ip helper?

yes correct - x.x.x.x (is the DHCP Server Address)

For each vlan that have dhcp local pool in SW use
Ip helper-address <dhcp server IP>
you need to remove the dhcp pool otherwise the client will get IP for dhcp pool not from server.
