We are planning to have 3 separate instances having standard licensing subscription of Atlassian within our organisation.
Is it possible to have same domain for each instance? For example, our domain is @email.com, can this be implemented across multiple instances?
In case they all have their own domains, for example, @email1.com, @email2.com and @email3.com.
Is it possible to configure SSO while all instances have their own domains.
