I just performed an upgrade for a CUCM version 9 to 11.5, after the upgrade i found that the tomcat and some other certificates were expired, i would like to regenerate them so they may not give me trouble later on, my question is:
Is there any consecuences to regenerating the tomcat, TVS, callmanager, etc certificates?
Do i need a maintenance window? is this going to affect the phones? if so wich of the certificates would do that?
I hope someone can help me with this data, i've tried searching online but i can't seem to find out exactly what impact will this have
