Kris,
Not quite sure what you mean by "in-place C6-C7 upgrade", unless you
mean something like the Fedora mechanism of doing a yum type update
which CentOS doesn't support.
I re-installed C7 over the C6 installation.
I then re-installed V3 which unfortunately installs backuppc with a new
I'm in the process of upgrading from Centos 6 to Centos 7.
A few days after I upgraded my BackupPC host to Centos 7 I upgraded
BackupPC to V4 which went well.
I then upgraded 2 more hosts to C7 and started getting 1 Xfer error for
these 2 hosts and I gather that this is what the error is.
