------------------------------------
{quote}I have not tested this at all, but "theoretically it should work".....

I have read a bit more about the RENAME command, and it actually does not
rename anything, it just adds an alias and makes it look like a rename happened
from the API's perspective. So I don't hink RENAME in its current form is a way
forward for your use case.
> Explore prohibiting aliases and collections from having the same name.

> URL: https://issues.apache.org/jira/browse/SOLR-13584
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Erick Erickson
> Priority: Major
>
> Allowing aliases and collections to have the same name is fragile and a
> potentially a data issue. I'll link in a few JIRAs illustrating this and one
> at least where the discussion gets long.
> Straw-man proposal to start things off.
> Deprecate this ability now, and enforce it in 9.0.
> We have to provide a graceful way for users to get themselves out of the
> following currently-possible use-case.
> * a collection C1 is created and all the front-end uses it.
> * users want to atomically switch to a new collection for various reasons
> * users create C2 and test it out.
> * users create an alias C1->C2
> Let's discuss.
