SSL certificate replacement in QRadar

Hi, we would like to replace default SSL certificate in QRadar deployment with one console and two event collectors in HA. There are few Wincollect agents too. If we replace default SSL certificate with an trusted certificate which is valid 2 years, should we expect any issues after replacing the trusted certificate again?
For example communication between Wincollect agents and console, or communication between collectors and console?Are there any problem in general with replacing default SSL certificates?

Thank you for clarification.
