At the moment I use a de-googled Teracube with e/OS which is also open source. Can anyone pls explain the advantages of moving to Graphene and what to do to transition from e/OS to Graphene? Many Thanks

GrapheneOS is far more secure than /e/ OS. They delay updates for months which leaves them unmatched and insecure compared to the stock OS.
There are also far more security and privacy features, you can check this comparison for more:

However, GrapheneOS does not support your target device.
