Hello, While I'm not certain this is the case, it *sounds* like the behavior you are seeing is related to a full reindex of the site.
After any database upgrade (via `dspace database migrate`), DSpace will trigger a full reindex of your site the next time you start up Tomcat (or whatever servlet container you are using). This full reindex may take some time (minutes or even hours, depending on the amount of content), but it runs in the backend. A reindex is required for major upgrades, as often the database structure changes, and your search/browse indexes then need to be updated based on those changes. You may wish to check your DSpace log files to see if you are seeing messages related to individual Items being "indexed". If so, this is the reindex processing each file, and once it is complete all your records should reappear in the search/browse. While it is reindexing you still can use the site, but not all records may appear (they each will appear as they are reindexed). And just to clarify, you no longer need to upgrade from one major version to the next. So, you should not need to upgrade from DSpace 3 to 5 to 6. You can now *directly* upgrade from any prior release to DSpace 6 (even from DSpace 1.0 -> 6.0 would work). The only requirement is that you need to make sure your database backend is upgraded first, to a compatible release. So, for example, if you are running a very old version of Postgres or Oracle, you'd want to upgrade that database backend to a recent version (as required by DSpace 6), and then you should be able to upgrade directly to DSpace 6 per the upgrade instructions at: https://wiki.duraspace.org/display/DSDOC6x/Upgrading+DSpace Hopefully that helps! If you have further questions, feel free to ask them on this list. Tim On Thu, Mar 8, 2018 at 12:04 PM <[email protected]> wrote: > Interesting...
