Release an rpm with a lower version than the existing one

[Alejandro Alvarez Ayllon]

Hi all,

Not so long ago I took over an rpm called dpm-dsi, being the released 
version 1.9.0.
The release of that version was decided by upstream.

However, now upstream has decided to deprecate 1.9.0 for the moment 
being, since they
consider it not stable enough. And they want to release an 1.8.* version.

So my question is: can I build and push to updates a lower version of an 
existing rpm,
and overwrite the existing one?

Regards.
