[EP-tech] Re: Help with migrating actual eprint documents from 2 to 3.X

Thank you so much!  Your instructions worked like a charm and I couldn't be happier.  

I've checked the epadmin command 'help' and it does not list this 'upgrade_add_files' option.  Thank you so much for pointing that out.

Hi Mike,
In EPrints 3, the file object was added. It needs to be generated before the pdf files can be downloaded.
Try the following instructions from point 3.


Migrate the documents folder

  • export EPrints 2 Metadata using the provided migration toolkit, make change to the exported XML if necessary.
  • import the XML to EPrints 3 server
  • copy over the documents folder to the new server
  • run epadmin upgrade, epadmin update [repoid] -- to upgrade the database structure
  • run epadmin upgrade_add_files [repoid] -- to add the file object introduced in eprints3

If the files are not downloadable (giving eprints system error), delete the file table in the database, then do epadmin update(create the files table), then rerun epadmin upgrade_add_files

The migration tool has also the option to migrate documents, did you use it?

I'm in the middle of migrating from a very old version 2 server to the
current version.  I've been able to use the migration tool to export
and import most of the data successfully.  I've had to massage some
things here and there but for the most part, it looks successful.

The only issue is that the pdfs and html documents of the eprints
themselves have not come across as well.  The entries are there, just
not the documents themselves.  I have tried recreating an example
document, using the same directory structure as it seems to be
expecting, but it did not work.  I was hoping to just be able to
wholesale copy the filesystem across and it would work.

Anyone have any suggestions please?
