[jira] [Commented] (SOLR-11127) Add a Collections API command to migrate the .system collection schema from Trie-based (pre-7.0) to Points-based (7.0+)

["Jan Høydahl (JIRA)" <ji...@apache.org>]

Jan Høydahl commented on SOLR-11127:
------------------------------------

Perhaps also that there should be a check on system startup in version 7.x which logs an ERROR log line if the system collection is not converted so people are alerted of the need before it's too late? That could be a new Jira issue for 7.5?

> SOLR-11119 will switch the Trie fieldtypes in the .system collection's schema to Points.
> Users with pre-7.0 .system collections will no longer be able to use them once Trie fields have been removed (8.0).
> Solr should provide a Collections API command MIGRATESYSTEMCOLLECTION to automatically convert a Trie-based .system collection to a Points-based one.
