Compatibility with TigerGraph 3.1

The following changes were made to the built-in roles in TigerGraph’s Role-based Access Control

The built-in role queryreader can no longer run queries that include updates to the database.
- To emulate the old queryreader role, create a role with all queryreader privileges, and also grant the WRITE_DATA privilege to the new role.
The built-in role admin can no longer create users
- To emulate the old admin role, create a global role with all admin privileges, and also grant the WRITE_USER privilege to the new role.
To learn more about role management and the privileges of built-in roles, see:
- Role Management
- List of Privileges

Compatibility with TigerGraph 2

Major revisions (e.g., from TigerGraph 2 to TigerGraph 3) are the opportunity to deliver significant improvements. While we make every effort to maintain backward compatibility, in selected cases APIs have changed or deprecated features have been dropped, in order to advance the overall product.

Data migration: A tool is available to migrate the data in TigerGraph 2.6 to TigerGraph 3.0. Please contact TigerGraph Support for assistance.

Query and API compatibility:

Some gadmin syntax has changed. Notably. gadmin set config is now gadmin config set. Please see Managing with gadmin.
Some features which were previously deprecated have been dropped. Please see V3.0 Removal of Previously Deprecated Features for a detailed list.
