[jira] [Commented] (IGNITE-7788) Data loss after cold restart with PDS and cache group change

    [ https://issues.apache.org/jira/browse/IGNITE-7788?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16381878#comment-16381878 ] 

Alexey Goncharuk commented on IGNITE-7788:
------------------------------------------

It is physically impossible to change the cache group for an existing cache.

We should add a check to validate the configuration and not start if such a condition is detected.
