Duplicated entries when importing xml from an older version

[ansanma]

By mistake, I've imported twice the same xml file containing site profiles. Now my ftp sites appears twice on site manager. I suggest you, if possible, to show a warning if the xml file contains sites with the same name/data of existing profiles and ask what to do (overwrite, import with another name (i.e. adding "(2)" at the end, or do nothing), to avoid duplicated entries when importing site profiles.
