[Q] ROM Update on CWM recovery topic

I have the MT7 TL10 international. The phone is rooted, BL unlocked and CWM installed. Today I received notification that an OTA update on B123 is available. I think I've read somewhere that the update will not work with CWM so I have to go back to stock recovery. I know how to do that but I just want to confirm with you experts whether or not IT is needed.
And in case I go back to stock recovery, do I just have to flash CWM again after the ROM update and it's all good again?
Thanks in advance for your feedback-much appreciated
