Hello Vaibhav,
>> can it is work when i create secondary ip on sub iterface ?
yes this can be done but I would see it as a temporary fix during a migration I would recommend to deploy one vlan per ip subnet if possible.
Hope to help

You can create svi interface in 3750 and assign ip address to them and 3750 will take care of intervlan routing.

Hi,
Conf t
int vlan
ip address
no shut

Hello Vaibhav,
first of all if they don't exist in vlan database you need to create the L2 vlan objects.
example:
conf t
vlan 2
name sales
exit
after you have created the L2 broadcast domain vlan 2 you need to associate it with access ports and/or L2 trunk ports.
then you can create the L3 object SVI
int Vlan2
desc SVI for broadcast domain vlan2
ip address 10.10.20.1 255.255.255.0
no shut
Hope to help
