Sounds like you did not read the migration guide ? There is a moverrd.sh script in the source hobbitd dir that will move all your old RRD files to the hobbit installation and reorder them for you.

It would be nice if Hobbit came with a tool, that you could run on your bb servers rrd directory, or a copy of it, and it would automagically copy the data to the host-based subdirs that hobbit uses.
I have a BB server that has been running for about 1.5 years. I have a Hobbit server I have been running in unison for several months, (via the BBRELAY option on the bb server). Soon I am going to totally decommission the bb server and use only the Hobbit server.
However, I do not wish to lose the trends history that the bb server has. Is there any sort of tool to migrate the rrd data from bb to hobbit? I started doing it manually, and it wasn't very fun.
The method I used to move the memory rrd data over is:
First off, I noticed that the directory structure of the ~hobbit/data/rrd directories and files is different from the ~bb/bbvar/rrd directories and files:
[*hobbit*]$ ls data/rrd/host.my-domain.net #Note that hobbit stores the rrds in subdirs disk,bigdisk.rrd *memory.physical.rrd* tcp.http.host.my-domain.net,.rrd disk,boot.rrd *memory.real.rrd* tcp.http.host.my-domain.net.rrd disk,root.rrd *memory.swap.rrd* tcp.ssh.rrd la.rrd procs.rrd users.rrd *memory.actual.rrd* tcp.conn.rrd (Hmm it looks like there is a duplicate tcp.http.host.my-domain.net,|.rrd? No idea where that came from, but I digress.)
[*bbhost*]$ ls bbvar/rrd |grep host #Note that bb stores all of the rrds in one dir host.my-domain.net.disk,bigdisk.rrd host.my-domain.net.disk,boot.rrd host.my-domain.net.disk,root.rrd host.my-domain.net.la.rrd *host,my-domain,net.memory.actual.rrd host,my-domain,net.memory.physical.rrd host,my-domain,net.memory.real.rrd host,my-domain,net.memory.swap.rrd* host.my-domain.net.procs.rrd host.my-domain.net.tcp.conn.rrd host.my-domain.net.tcp.http.host.my-domain.net.rrd host.my-domain.net.tcp.ssh.rrd host.my-domain.net.users.rrd
So it looks like on the bbhost, for some reason, the host name is comma delimited....but only for the memory rrd files? This is strange. Ah well I just need to get them to the hobbit server, and with the proper filenames, and in the proper subdirs. So I scp'd all of the memory rrd files to the hobbit server into /tmp/mem, and then:
[hobbit] $ cd ~hobbit/data/rrd; for hostdir in
ls; do BBHOST=echo $hostdir|sed 's/\./,/g'; cp -vf /tmp/mem/$BBHOST.memory.real.rrd $hostdir/memory.real.rrd; doneI repeated this command for the "swap", "actual", and "real" files. The sed command was to generate the comma-delimited filenames I needed to find the files. This command copied all of the memory rrd files into the proper subdirs.
I'm not sure why only the memory rrd files on my bb server are comma-delimited. Maybe some misconfiguration I did in the past? The memory graphs look normal in the trends column though...ah well.
