Increasing maxMergedSegmentMB value

[Zheng Lin Edwin Yeo]

Hi,

I would like to find out, when I increase the maxMergedSegmentMB from 10240
(10GB) to 15360 (15GB), will all the 10GB segments that were created
previously be automatically merge to 15GB?

This setting is part of my mergePolicy setting, which I am using
TieredMergePolicy.

        <mergePolicy class="org.apache.lucene.index.TieredMergePolicy">
          <int name="maxMergeAtOnce">10</int>
          <int name="segmentsPerTier">10</int>
  <double name="maxMergedSegmentMB">15360</double>
        </mergePolicy>


I am using Solr 5.4.0.


Regards,
Edwin
