cucm 11.5 regenerate expired certificates

[Translator]

Hi, experts,

Trying to regenerate an expired certificate due to a late check while running cucm 11.5.
Can I restart the service by regenerating the expired certificate?
Or do I have to get a new one when it expires?

Expired certificates are listed below.
CallManager, TVS, ipsec, CAPF

Please check old forum posts. This topic has been discussed I don't know how many times.
And I think, @Roger Kallberg wrote a forum blog about this topic.
