Hi There
I have recently upgraded a solr database from 7.7.1 to 8.7.0 and not wiped the
database and re-indexed (as this would take too long to run on site).
On my local windows machine I have a single solr server 7.7.1 installation
I upgraded in the following manner
Installed windows solr 8.7.0 on my machine in a different folder
Copied the core related folder (holding conf, data, lib, core.properties) from
7.7.1 to the new 8.7.0 folder
Brought up the solr
Checked that queries work through the Solr Admin Tool and our application
This all worked fine until I tried to update a record which had been created
under 7.7.1. Instead of marking the old record as deleted it effectively
created a new copy of the record with the change in and left the old image as
still visible. When I updated the record again it then correctly updated the
new 8.7.0 version without leaving the old image behind. If I created a new
record and then updated it the solr record would be updated correctly. The
issue only seemed to affect the old 7.7.1 created records.
An example of the duplication as follows (the first record is 7.7.1 created
version and the second record is the 8.7.0 version after carrying out an
update):

}}
I checked the solrconfig.xml file and it does have a uniqueKey set up
<field name="id" type="string" indexed="true" stored="true"
required="true" multiValued="false" />
<uniqueKey>id</uniqueKey>
I was wondering if this behaviour is expected and if there is a way to make
sure that records created under a previous version are updated correctly (so
that the old data is deleted when updated).
Also am I upgrading solr correctly as it could be that the way I have upgraded
it might be causing this issue (I tried hunting through the solr documentation
online but struggled to find window upgrade notes and the above steps I worked
out by trial and error).
Many thanks
Matthew
