The Organization Where Copado Is Installed Is Changing Instance
Salesforce may decide to move your organization to a different instance with upgraded hardware and software within your region in order to improve your org’s performance and better position it for growth in the future. This means that your organization will change for example from instance NA37 to NA78.
If Copado is installed in the organization that is changing the instance, all the org credentials in that organization will have to be validated again right after the instance migration. This is only applicable to org credentials pointing to the org that is being migrated.
