[Dspace-tech] DB update problems

[IdeaFix]

After upgrade from DSpace 3.3 to 5.2 I run "dspace -f -d -v" and get this
output:

I have a problems with "dspace cleanup -v", there is some bitstream ids,

Re: [Dspace-tech] What's the plan for "Browse by" functionality?

[Alan Orth]

That's good to hear, Tim. I was mistaken about "Browse by" still using
Lucene. Recently I found some metadata out of date on our DSpace instance,
and it turns out I had to re-activate the Lucene indexing cron jobs which I
had disabled after upgrading to DSpace 4.x last year. But actually this was
for one of our third-party modules, not "Browse by".

Now to pressure the developer of the third-party module to update to
Discovery. ;)

Regards,

Alan
