I want to change my ic880a to IN865 using chirpstack os

hello,
i am using chiprstack os with raspberry pi and ic880a my device is working fine with EU868 now i want to change it to IN865 i have changed the channel configuration

LoRa concentrator configuration.
[gateway.concentrator]

Multi spreading-factor channels (LoRa).

multi_sf_channels=[
868100000,
868300000,
868500000,
disable,
disable,
disable,
disable,
disable,
]

LoRa std channel (single spreading-factor).

[gateway.concentrator.lora_std]
frequency=disable

FSK channel.

[gateway.concentrator.fsk]
frequency=disable

and changed my model to imst_ic880a_In865 under general configuration

is that enough for changing the frequency according to my region or do i have to do another change?
or is there any other method for changing the frequency?
thanks and regards
