Working with Merge Sessions
Within the Requirements Editor tool, you can merge content distributions to your existing repository, allowing you to selectively retain any modifications you have made to your content.
New Merge Session
A new Merge session can be created by selecting New Merge Session from the File menu.
Open Merge Session
An existing/previous session can be opened by selecting File > Open Merge Session.
The previous session file has an extension of .msession. When opening an
existing Merge Session, identify the msession file located in the folder created
during the New Merge Session.
Close Merge Session
To close your Merge session without closing Requirements Editor, select File > Close Merge Session.
