How to export a large Schema from one HANA environment to another?

I have a schema with one very large table of 43m records and a number of other smaller tables.

I would like to export this schema to another HANA environment but am getting errors using both the client and server export options:

- client export results in an error that I exceed the max in-memory lob size (SAP DBTech JDBC: [2]: general error)

- server export results in an error that it could not create export path, even though I used chmod 777 (SAP DBTech JDBC: [2048]: column store error: table export failed)

Can anyone suggest what the best way to transport data from one HANA environment to another please?

Thanks.
