Adding VLAN between Nexus vPC and Catalyst3750 in a HOT

I have a setup where 2 redundant Nexus3Ks are connected to 2 redundant Catalyst3750.

Each Catalyst is connected to both Nexus on a port channel. On Nexus side vPC is configured.

There are already 4 vlans working on the link between Catalyst and Nexus.

Now I want to add a 5th VLAN, can it be done without impacting any traffic? What could be the impact? Any suggestions?

Adding VLAN on port channel is enough?

Current configurations are below

#############################

interface port-channel10                                                  <---Port Channel towards other Nexus

  description Po10 to FDP-R02

  switchport mode trunk

  switchport trunk allowed vlan 162-168,210-238,246-257,260-261,501-506,509-517,851-852,1253

  spanning-tree port type network

  no negotiate auto

  vpc peer-link

interface port-channel3                                        <---Port Channel (vpc based) towards Catalyst

  description Po3 to Cat3

  switchport mode trunk

  switchport trunk allowed vlan 246,249,252,852

  spanning-tree port type edge trunk

  no negotiate auto

  vpc 3

interface port-channel4                                        <---Port Channel (vpc based) towards Catalyst

  description Po4 to Cat4

  switchport mode trunk

  switchport trunk allowed vlan 246,249,252,852

  spanning-tree port type edge trunk

  no negotiate auto

  vpc 4

Now the new VLAN need to be added is 258. And I have prepared below configurations.

Can you please tell me with below configurations if there can be any impact? Or regardless of the below configurations what can be the impact?

vlan 258

  name prv_cms

interface port-channel10

  switchport trunk allowed vlan 162-168,210-238,246-258,260-261,501-506,509-517,851-852,1253

interface port-channel3

  switchport trunk allowed vlan 246,249,252,852,258

interface port-channel4

  switchport trunk allowed vlan 246,249,252,852,258
