Dear Phany,
You can upgrade the HyperMetro storage systems if needed.
For the upgrade procedure and precautions, see the BC&DR Solution Upgrade Guide (Active-Active Mode) corresponding to your product model.
To obtain the document, you can access https://support.huawei.com/enterprise/ and choose PRODUCT SUPPORT > Enterprise Data Center > Storage Solution > BC&DR Solution. Then search for the document in the search box.
I hope this can help you.
