As a workaround, perform the following steps:
- Go to the top of your Content Matrix console and click on the Settings tab. Then, click on the Enabled Advanced Mode button on the top ribbon.
- Connect to your source SP2007 Site Collection using the NWS (remote Native Web Service adapter.) Normally we would not use this adapter to copy content, but in this instance it's for troubleshooting.
- Right-click on that new connection made with the NWS adapter, and choose Copy Site.
- Right-click on your target Site and choose Paste Objects > Navigation. Run the migration job.
