"Import path is not set" when importing

Hello,

I'm trying to migrate from ZCS Open Source 7.2.0 on a Debian 5 64bits to a ZCS Open Source 7.2.1 on Ubuntu 10.04 LTS.

Export works fine, I transfer files via rsync between servers. I install Zextra suite on destination server. When I want to "Import backup", I set path of my data, I choose domains I want to import and when I click on "Next", Zimbra says "Import path is not set.". No more details and no errors in mailbox.log.

Can anyone help me ?

Thanks in advance !
