Changing Solr Schema with Data
Hi,
I am facing an issue where I need to change Solr schema but I have crucial
data that I don't want to delete. Is there a way where I can change the
schema of the index while keeping the data intact?
Regards,
Salman

All crucial data that you don't want to delete should be stored in a
non-Solr backing store, either flat files (e.g., CSV or Solr XML), an
RDBMS, or a NoSQL database. You should always be in a position to either
fully reindex or fully discard your Solr data. Solr is not a system of
record database. Was someone telling you something different?

What shalin says is solid and will work with solr 5.x as well as 3.x
You could do a little poc if you want to be absolutely certain. Shouldn't
take you very long.
Your only concern will be that your old docs won't be matched against
queries matched against the newly added fields.

Thanks guys for your responses.
@Shalin: Do you have a documentation that explains this? Moreover, is it
only for Solr 5+ or is it still applicable to Solr 3+? I am asking this as
I am working in a team and in some of our projects we are using old Solr
versions and I need to convince the guys that this is possible in the old
Solr as well.
Thanks for your help.

Salman

Adding new fields is not a problem. You can continue to use your
existing index with the new schema.

You can say that we are not removing any fields (so the old data should not
get affected), however, we need to add new fields (which new data will
have). Does that answer your question?

Is the schema change affects the data you want to keep?
