During the AGC webinar, it was stated that migrating from commercial cloud AGC will not be done using JCMA; the tool for that has not yet been released.
Does this mean that migrating from DC to AGC will be possible using JCMA?
Atlassian Government Cloud has just been announced at Team '25 and at this stage you can request to join a waitlist to be allowed into the Early Access program (from the link you shared in your question):
Since this is early access at this point - and even with a waitlist for that - you'll have to sign up that way to get included the earliest as possible. You won't be able to migrate on your own through a different path (at this point).
I am quite sure that the EAP is being used to test and prepare the migration tooling prior to GA.
As of now, JCMA (Jira Cloud Migration Assistant) does not officially support migrations from Data Center to AGC or FedRAMP. While Atlassian’s FAQ mentions that migration tooling is available, it likely refers to internal processes or tools that aren’t publicly released or fully documented yet. During Atlassian’s AGC webinar, they noted that migrations from commercial cloud to AGC or FedRAMP aren’t supported via JCMA either.
In cases like this—where native options are limited or unavailable—organizations often use external migration tools that give them more control. OpsHub Migration Manager, (OMM) an Atlassian Partner is helpful not because they’re plug-and-play, but because they:
Execute phased or one-time migrations with no disruption and zero downtime
Allow you to carefully map data (projects, users, attachments, comments) across systems with different configurations
Ensure completeness and consistency—important when migrating into a compliance-bound environment like AGC
Provide logs and traceability to support auditing or internal reviews
This approach is especially useful when you need to migrate without relying on in-app assistants and want to avoid loss of context, history, or relationships during the move.
Wanted to post an update on both migration from DC and from Commercial Cloud per my recent discussions with Atlassian (early August 2025):
1) Data Center to Atlassian Government Cloud (AGC) migration: can be done using JCMA with a feature flag. this is already available.
2) Commercial Cloud to AGC Migration Tool & GA Timeline: The tool for migrating from Commercial Cloud to AGC is new and currently in beta.
The latest guidance is that General Availability (GA) for this migration tooling is targeted for September 2025. This aligns with the broader AGC GA timeline and is being validated with early customer migrations to prove out the process before public launch
