Upgrade AMSv5.0 IP Adress change / Roon NAS Backup

Hi, I have 2 questions.

  1. After upgrading to AMSv 5.0 the IP Adresss of my CX doesn’t changed. Is it necessary to change the IP ?

  2. After ther upgrade to AMS v 5.0 the Roon Backup file folder on my NAS in the network can’ t be reached. Host could not be found !

Any ideas, thanks Carsten
