The Client Merge command lets you merge all elements from Client B into Client A. It’s quicker than Import from Client if you want to import all library entries (and copy over database files, which Import from Client does not do). Client Merge always "appends" objects (copies without replacing anything, renaming as necessary to avoid change collisions) unless the objects exist in both clients with the same ID#, date of last mod, and creation date. Such truly identical objects are simply not copied.

Client Merge’s primary use is to merge two unique ProVal clients (that is, they aren’t modified copies of each other), such as for business line 1 and business line 2, together so the results can be combined within ProVal.
