Impact

This maintenance will not cause any service interruption, and the service will remain available as usual.
Data transmission from devices and applications will not be affected.

However, if you are using custom programs that utilize the T&D WebStorage Service API, they may be affected depending on the encryption methods used in your environment.
In such cases, please update your environment to support the latest standards.
