After posting my original message I opened an SR for the same issue.  Support consulted with back-end engineering and the response was, "EE came back and said it should be fine to rename".  Since then, I have renamed many Log Insight VMs on VxRail without problem.  
I want to know if it's supported to change the Log Insight VM name in any version of VxRail.  We currently have version 4.5.215. I know there are renaming procedures in SolVe for just about every other component, but there's no mention of the Log Insight VM.  Same with the Administrator Guide.  It mentions renaming other VMs, but doesn't mention Log Inisght. KB article 474897 for VxRail 3.x explicitly says that renaming the Log Insight VM was not supported in that version - [URL] But, later, in versions 4.0.100 thru 4.0.300, support for renaming almost every component was introduced, but the docs don't say anything about the Log Insight VM.  Please let us know if renaming it is now supported.  Thanks.
Can we rename the Log Insight VM in VxRail?
