When you upgrade eMessage, the
eMessage mailing interface is not available. You cannot configure or start new mailings. Mailings that you have already started will run, but you cannot monitor, pause, or stop them.
When you upgrade eMessage you must temporarily stop the RCT.
During the upgrade, you might experience some delay in the availability of mailing response data. However, the data is not lost. IBM® EMM Hosted Services queues response and contact data during the time that the RCT is stopped. When you restart the RCT, all the accumulated data is downloaded.
