hi,
just a sanity check, i just need to change or update the VLAN on the ASA 'outside' interface and add/allow the VLAN on the switch trunk.
it's troublesome to negate the whole subif since the nameif and its route, NAT related configs will be removed and need to add them back.
just to make things simple, do i just straightforward overwrite on the ASA subif with the vlan 150 command?
SW:
interface GigabitEthernet1/0/1
switchport trunk allowed vlan add 100
switchport trunk allowed vlan remove 150
ASA:
interface GigabitEthernet0/1.150
vlan 100 <<< PREVIOUSLY VLAN 150
nameif outside
security-level 0
<IP ADD SM>

Correct, just overwrite the old vlan 150 with vlan 100.
