Question about Driver Container Updating

[sakaia]

Is this container consider replacing. (like updating)?
For example
If some version (for example 5.2) is running, and updating (for example 5.3) is effective on some host server?
Of course, during the updating all containers are stopped. And at this moment this is NOT real issue.
I am wondering driver installation/uninstallation process is considered in driver container or not.(from seeing the entrypoint.sh, it is not considered.)
