The necessary course of action varies depending on your plan:
Team and Studio (if you're using cloud storage) - nothing should be changed.
2. Studio (if you're using local storage)
Main menu > Tools > Administrator...;
File storages tab;
If necessary, update the contents of the DNS name or IP address field with the new values;
Check the port settings on your router or proxy. Calls to ports 45431 and 4080 should be redirected from externally to your server with Cerebro file storage.
Same actions as in 2;
Please contact our Support with your Universe name and the new IP address or DNS name: https://cerebrohq.com/en/support/. We will add your new IP address or DNS name to our global database. Then users will be able to connect using Cerebro's default connection settings;
If you're using the old authorization method (in the user connection settings, Use database address is checked), give your users the new address to use in Connection settings.
