Changing logical name - Impact on Sub-interface- FTD

Dear All,

I was trying to add a logical name to one of our internet faced physical interface to bring it to high availablity monitoring. But we have a sub-interface under this physical interface which is the actual internet logical interface with IP configured. Since I want only the physical interface to get monitored and don't want to have the logical IP-sub-interface for monitoring I did this.

But before deploying I want to make sure this won't impact the logical sub-interface connectivity or do I need to do this with maintainance window. Since there are many challenges to get a maintainance window I would need to check if this change doesn't interrupts or disconnects if we push it during production.

Does changing the logical name of a physical interface have any disconnections on the sub-interface..? can anyone confirm pls.
