Can we upgrade from Current CAL S/4 HANA 1809 Version up to 1909?

Hello,

We have installed, customized and entryed documents CAL S/4 HANA 1809 on AWS for several months.

Now we would like to upgrade CAL S/4 HANA 1809 to 1909 on AWS.

Can we upgrade and could you let us know how to do?

According to the CAL site, we can only create new S/4 HANA 1809 and batch-input for post documents.

In Japanese as below,

AWSで、CAL S/4 HANA 1809 を使ってきましたが、データが入っているため、CAL S/4 HANA 1909に

バージョンアップできないでしょうか？できる場合は、方法を教えてください。
