>          Issue Type: Bug
>      Security Level: Public(Default Security Level. Issues are Public) 
>          Components: update, UpdateRequestProcessors
>    Affects Versions: 8.8.2

> We upgrade Solr7.7.2 to Solr8.8.2, keep using the Solr 7 index data, the query operation is fine. But when we try to add the doc (with the same doc id, actually is an update operation) to Solr8, we actually see 2 doc with the same id, which means the update did not remove the Solr7 doc.

>  
> Below is the schema.xml configuration:
>  
> {code:java}
> <field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
> <field name="_root_" type="string" indexed="true" stored="false"/>
> <uniqueKey>id</uniqueKey>
> {code}
>  
> Also add nested field in Solr8
> {code:java}
> <fieldType name="_nest_path_" class="solr.NestPathField" />{code}
>  
> I can see in Sol7 code
> {code:java}
> DirectUpdateHandler2.updateDocOrDocValues{code}
> use the idTerm as updateTerm, but in this case Solr8 use rootTerm as the updateTerm. is this an expected behavior?
