Yes, the recalculation at the end of that upgrade script is necessary.
In 3.0, we made some changes to the way catalog searches determine
record visibility, and this part of the script recalculates visibility
to fix a few search issues that were discovered in the 3.0 release.
Without recalculating visibility, you'll find that some records for
electronic resources or those that have a bib source (which cover almost
all records in our system) will appear in searches when they shouldn't.
Having said that, I think we can speed up that upgrade script. We had a
similar calculation in the 2.12 to 3.0 upgrade script, and I one point
we made a change to disable various triggers before performing the
calculation. My understanding is that the calculations perform much more
quickly with those triggers disabled. See the changes at:
I'm going to file a bug to see if we can make a similar change for the
3.0.2-3.0.3 upgrade script.

During my last test cycle we ran into an issue upgrading from 2.10 to
a newer version with an update script that was setting the 901$sfor
bib records. This took an extended amount of time to complete. Well
now, in testing our upgrade to the 3.0 series part of the 3.0.2-3.0.3
version upgrade script took over a week to finish in testing, which is
a big issue for updating production.
Is it possible to comment out/remove the offending part of the upgrade
script and not have any issues with the new system after the upgrade?
Could it be the last part of the script in lines 277-291 of the
upgrade script taking this long (line 290 perhaps)?

Wondering if others have met something similar and how they dealt with
it so as not to cause issues upgrading a production system and
minimizing down time. We typically run our upgrades on a Sunday
morning and all Evergreen related services are only down for about
half a day and usually back up before 10am Monday worst case.
