There is Index db path collision check for summaryHomePath starting from version 7.2.X

Possible affect to customers:
Any customer that has not configured with summaryHomePath or just configured with volume referencing for any index, I.e homePath = volume:hot at downward 7.2.x version

Symptom:
Indexer won’t be able to start after upgrade Or bundle push for indexes.conf change without the required configuration.

Error:
Problem parsing indexes.conf: Cannot load IndexConfig: index= Path=$SPLUNK_HOME/INDEX_NAME/summary given as value of param=homePath collides with value of param2=summaryHomePath of index2=

Reason:
Every index is going to use same summary index path(location).

To fix the issue:
Adding summaryHomePath = volume:hot/$_index_name/summary to every index configuration.

Please see our doc:
https://docs.splunk.com/Documentation/Splunk/latest/Admin/Indexesconf

summaryHomePath =

It is recommended that you specify the path with the following syntax:
summaryHomePath = $SPLUNK_DB/$_index_name/summary
At runtime, Splunk expands "$_index_name" to the name of the index. For example,
if the index name is "newindex", summaryHomePath becomes "$SPLUNK_DB/newindex/summary".
May contain a volume reference (see volume section below) in place of $SPLUNK_DB.
Volume reference must be used if data retention based on data size is desired.
CAUTION: Path must be writable.
If not specified, Splunk creates a directory 'summary' in the same location as homePath
