<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"> <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
into a new ArchivesSpace instance rather than into a new repository. That brings me to my questions:<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p>1.<span style="font-size:7.0pt"> </span>Can I migrate data from Toolkit to a new repository in ASpace rather than into a new instance of ASpace? Is that even a good idea? I have my doubts, given the potential to corrupt the existing data.<u></u><u></u></p>

<p class="MsoNormal">The AT migration tool cannot migrate data into a specific Repository. Rather it will copy all the records in the AT database (including any repository records) into the ASpace instance without regard to the data already in there. As such,
this is not a migration strategy that's recommend or supported.<u></u><u></u></p>

This can be done using the REST API of ASpace, but you will have to write a custom migration tool to do this.<u></u><u></u></p>
