have a duplicate repository record, then a whole bunch of records will not migrate.

<br>
As such, we don't officially support this approach since it cannot be guaranteed all your records will migrate correctly. That said, unless the two AT database are similar in content then there should only be a small number of duplicate and linking errors which
can be fixed manually.<u></u><u></u></p>

<p class="MsoNormal">Arizona State University recently absorbed the Thunderbird School of Global Management, which means that we are in the process of adding their collection metadata to our collection
metadata. ASU migrated to ArchivesSpace in late 2013 and put it into full production in early 2014. Our instance is currently at version 1.1.0 (although I have a request in to update it) and has eight repositories. Thunderbird is running Archivists Toolkit
version 2.0 (I’m not sure what update).<u></u><u></u></p>

<p class="MsoNormal">Basically, what I want to do is add a ninth repository for Thunderbird and migrate the data into it. I looked over the migration guidance, but it seems to assume that one is migrating
