Does the Atlassian Enterprise license grant access from multiple IDP's to multiple Instances

[Simon Hughes]

We have recently acquired a company that uses Atlassian the same as us. Both orgs are on the premium license and use their own identity

Which of the following statements of my understanding are true to avoid double license counts?

• An upgrade to enterprise allows both sets of users to access each others instance via their existing IDP. After the purchase of the license does that mean Atlassian reprovision access to both Atlassian instances using each set of identities over say a weekend
• An upgrade to enterprise license allows one IDP to access multiple instances. Meaning we would have to provision additional accounts from the preferred IDP and request Atlassian to repoint the old identity accounts to the new identity accounts again over a quiet scheduled time

Thanks

In Atlassian Cloud, the Enterprise plan gives you **centralized user management across multiple instances** through Atlassian Organization and Atlassian Access, but it does not natively support multiple IDPs for the same org at the same time. You can connect **one IDP per Atlassian Organization**, so if you want users from both companies to access each other’s instances without duplicate licensing, you’d need to consolidate the instances under a single Atlassian Organization and single identity source. This usually means migrating one company’s accounts into the chosen IDP and syncing via SCIM, rather than Atlassian “reprovisioning” accounts on the fly.
