Upgrade from Sophos UTM 9.503-004

To update you have to download all the new Update Files. You cant Jump for example from 502 to 504.
I had an old Iso DVD, and the current update was so high (about 9 files to download)  

Can only be updated from revision to revision. If I have version 9.503-004 now, i have to look for an FTP update file starting with u2d-sys 9.503004--. 
But this is not the FTP. I can not update from CD, i have about 30 customers using Sophos UTM Essential Firewall and the idea that i have to go 
everybody and update it with a "new installation" is out of reality :)

I see your problem, there does seem to be a file missing from ftp.astaro.com/UTM/v9/up2date/

The solution is to contact Sophos, since they maintain the download site.

Ahoj Marek and welcome to the UTM Community!

I call it the "version-change trick."  Do you already have u2d-sys-9.415001-505004.tgz.gpg in /var/up2date/sys?  Probably not, so do the following as root at the command line:

 Wait a minute and then apply the 9.415-to-9.505 Up2Date in WebAdmin.
