[EP-tech] Eprints migration


I'm trying to migrate the data from an old eprints server (ubuntu 10.04, eprints 3.3.7) to a new one (ubuntu 16.04, eprints 3.3.15). Maybe worth mentioning i had some problems when trying to install eprints and i used the steps from here http://www.eprints.org/tech.php/22140/attachment/message.html to successfully install it.

I moved the repository to the new server, but when i use the import script on the XML I exported from the old server, i get this error:

eprints@myserver:~/bin$ ./import library --verbose --migration archive XML library.xml

I also tried the method on your wiki (https://wiki.eprints.org/w/Moving_a_repository) with the mysqldump but when i do "./bin/epadmin upgrade library" i get the same error.

If you have any idea what the problem might be i would be very glad.
Thank you.
