Hello,
Are there any reefs in upgrading to the toaster from another qmail installation? I mean, should I backup anything (and restore after the installation) or just install the toaster onto the previous installation? Currently I use qmailrocks' installation on two servers, but I badly need chkuser functionality that is absent in it.
Just backup /var/qmail/* directories, /var/qmail/control/* might be enought, but this way you can restore working system without pain.
Also backup /home/vpopmail/* (contains all mails, userinformation)
