Globus Connect Server version 5 (GCSv5) provides new capabilities and enhancements for both administrators and users and offers platform features that allow developers to build interesting data management solutions. Among other improvements, GCSv5…

-  ...replaces user certificates with OAuth based authentication,

-  ...adds HTTP/S access to data,

-  ...simplifies support for multiple storage types via a DTN pool,

-  ...provides higher levels of assurance for managing protected data,

-  ...synchronizes and backs up endpoint configuration information, and

-  …adds support for cloud storage from vendors such as Google, Microsoft, and Box.

For the past year, GCSv5 has been used for all newly created Globus endpoints. Now we are ready for the next phase of our transition to GCSv5: the migration of existing GCSv4 deployments to v5. Globus provides upgrade and migration tooling that extracts configuration information from GCSv4 and applies the settings to a new v5 deployment, preserving the unique identifier (UUID) of the endpoint to ensure continuity of access for users.  

We are rolling out migration in cohorts to ensure we provide adequate and timely user support for the wide variety of possible GCS deployment configurations. Migration will be supported first for managed endpoints organized by cohorts in the order listed below, followed by other types of deployment.

Cohort Number of DTNs Sharing Authentication Method
1 Multiple Not Enabled CILogon
2 Multiple Not Enabled MyProxy OAuth
3 Multiple Not Enabled MyProxy
4 Multiple Enabled Any
5 Single Any Any


Administrators of GCSv4 deployments that meet cohort criteria will be contacted directly when we are ready to support migration of their deployment.  Cohort 1 migration begins November 15, 2021.

If your GCS deployment does not have any shared endpoints and you don’t require preservation of the endpoint UUID, then you don’t have to wait for migration tools.  You can replace your GCSv4 endpoint with v5 today by setting up a new GCSv5 deployment and shutting down the old GCSv4 endpoint.

Please contact support@globus.org if you have any questions.
