Hello Solr users,

We are currently in the process of moving from Trie* classes away and are 
having some questions how todo the migration.
During that we are having some questions, where we cannot find an answer in the 
documentation.

1.) Are these equivalent field definitions?

Old:

<fieldType name="long" class="solr.TrieLongField" precisionStep="0" 
positionIncrementGap="0”/>

New:

<fieldType name="long" class="solr.LongPointField" docValues="true”/>

I cannot find anything about precisionStep and positionIncrementGap for the new 
fields and assume that docValues will take care of that in some way?

2.) Do we need to reindex after the scheme change?

We have a large collections and are serving requests 24/7. Is a full index 
required or is Solr/Lucene able to handle both field types until everything is 
updated?


Thank you
Björn
