I considering replacement older OpManager to new one.

Please let me know the following information for consideration.

1) Could you please tell me the specific steps to migrate the alert data and performance data from the old OpManager (version 12.4) to the new OpManager (version 12.5 or later)?

2) Could you please tell me how to check the capacity of alert data and performance data in the current system?

3) It seems that there is a privileged account such as Admin or root as the login user of the management console, but is it possible to change the user name of the privileged account?

4) Is it possible to change the following settings in the password policy?

Example) Supports TLS versions 1.2, 1,3. 

Thank you for your cooperation.
