Hello.
I have a mongodb cluster installed on my own Linux servers (version 4.0).
If I do the system upgrade of the MongoDB cluster to versions 4.2 then 4.4 then 5 then 6.0 i see that some indexes have been renamed.
Example some of them with name index_country_1 are renamed to index_country.
Is there a reindexation during the system upgrade? Why can explain this renaming?
Is it normal?
Thank you for any help you can give to me.
Regards
