[EP-tech] Eprints not working after migration to a new server



Hi Norbert,

> ... pronom_internal.pl is from preservation toolkit at eprints bazaar.
I fear your error(s) are caused by a somehow outdated bazaar plugin:
Following https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F6265673%2Fperl-using-a-hash-as-a-reference-is-deprecated&data=01%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7Ccb22201c058b490224a508d74b283e58%7C4a5378f929f44d3ebe89669d03ada9d8%7C0&sdata=Pu7o%2FHzU39suWVfv59XXyf80XCNvKvYOjqKojRjnrRo%3D&reserved=0 I modified some lines in your configuration file to get all(?) running for EPrints 3.4.0 basing on perl 5.24.1 at Debian 9.8, but hope that someone from ECS will check for further updating!

Here are my modifications:
diff pronom_internal.pl_mod pronom_internal.pl_org

Obviously the new perl is more strict. BTW: Do you have all necessary modules updated?

Without _any_ guarantee I recommend to just install the _modified_ plugin:
1. Move all remaining files listed in origin:EPrintsRoot/lib/epm/preservation_toolkit/preservation_toolkit.epmi to new server using /usr/share/eprints3/lib/ as prefix for all file paths.
2. Put the modified pronom_internal.pl into EPrintsRoot/archives/repoID/cfg/cfg.d/, but don't forget the original pronom.pl in the same directory.
3. restart apache

yes, but after action item 1 this will be healed!? Or are there still some unmoved files on the origin server?
