Avamar Certificate expired

Hi, I wanted to know if anyone could help me with this type of report:

Event Code = 31056 Event Date/Time = 02/16-09:16:41.00575 EventType = ERROR Event Severity = PROCESS Event Summary = The certificate will be expired soon. Software Source = MCS:ST Hardware Source = node-xxxxx-ct Administrator Server = node-xxxxx-ct Administrator Server version = 7.5.1-101_HF290938_3 Avamar Server = node-xxxxxxxx-yy.zzz-wwwwwww.net Avamar Server systemid = 1521030045@00:60:16:72:49:0C Avamar Server version = 7.5.1-101 Backup & Recovery Manager Url= Data Domain System = dd-xxxxxxx-ct.yyy-wwwwww.net Data Domain System OS version = 5.7.3.0-548132 Data Domain System serial number = CKMyyyyyyyyy Event Data = Entry key = Expire date Entry value = 2023/03/13 Entry key = Certificate name Entry value = RSA Root CA Entry key = requestor Entry value =

I wanted to ask you

1) at the deadline what problems could arise?

2) Can the expiration date of the certificate be changed or must it be regenerated if necessary? and if so how to do it?

Thanks to all in advance
