I just completed, or thought that I had completed, migrating all mailboxes from our 2010 &gt;&nbsp;2013 CU9 environment. &nbsp;I have noticed that there are multiple system mailboxes and only one was moved over during migration. We have issues occurring in our new environment such as not being able to do eDiscovery. I have all system mailboxes now copied over to 2013, but before I complete the move request, I just want to make sure that there will be no negative impact during business hours, or if I should wait until after hours to complete the request. &nbsp;Any info would be greatly appreciated.<br />

Migrating System Mailboxes During Business Hours

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
