The merge cannot be performed if there are broken or missing links. Therefore, you should check the links in Site #1 and check the links in Site #2.
Refer to the appropriate section for instructions:
You use the Link Configuration tool to verify that each Site #1 primary domain or a Site #1 secondary domain has an inbound link from the Site #2 external domain.
In ConsoleOne, make sure you are connected to the Site #2 GroupWise system.
Click to launch the Link Configuration tool.
In the domain list, select the external domain (worksheet item 13) whose inbound links you want to check.
Check the Inbound Links window (displayed by default for an external domain) to make sure that a direct link icon labeled with a Site #2 secondary or primary domain name is displayed there (worksheet item 8).
An inbound link to the Site #1 external domain from a Site #2 domain is required for the merge to proceed.
(Conditional) If the link is incorrectly configured, double-click the Site #2 domain name to display the Edit Domain Link dialog box.
Edit the fields as necessary (worksheet item 20), then click to save your changes.
