This section applies only if the systems you are merging cannot be directly connected and you must use temporary database copies (worksheet item 4).
You need to create temporary holding directories where you can place copies of the Site #2 wpdomain.db files for the primary and secondary domains (worksheet item 8).
For Site #2, create separate directories for the primary domain and each secondary domain.
You create these directories in Site #2 to accommodate releasing the secondary domains. Each wpdomain.db file must have its own temporary directory (worksheet item 21). Name the temporary directory so that you can keep track of which domain the database belongs to. One suggested strategy is to create a temporary directory and then create subdirectories in it that match the names of the primary and secondary domains.
Make a copy of each wpdomain.db file in its appropriate holding directory.
Make a copy of the gwdom.dc file from the domain subdirectory of your software distribution directory in each holding directory.
