I have searched through all the threads but there was no solution or suggestion for the user accounts maint.

I am using Open Source Edition but I found that a thread was talking that it is required to reset the password even using the Network Edition.

I found that I can use "zmprov gga" to get all the user accounts including the hash password. So is there any approach to restore the user account by using such information.

Now I am facing this problem. I want to migrate all the stuff from one Zimbra server to another Zimbra server using diff OS. I got email backup on hand but no idea how to deal with the account. I don't want to tell the user to use the new password.
