I went though a similar exercise last year when I upgraded from a Knoppmyth installation to Mythbuntu. Combined BE/FE as well<br><br>It was really easy and relatively straightforward. All my recordings, music, video etc was all on a seperate partition, as was my database backups.<br>
<br>I just made sure I had a couple of up to date backups, including /etc /home, and /usr/local/bin. <br><br>Installed mythbuntu (64 bit)over the existing / partition<br><br>Mounted /myth, and added it to fstab<br><br>restored the .mythtv directory for the mythtv user.<br>
<br>Restored my database (largest pain as the schema upgrade to 0.22 was not smooth, but that was a mythtv issue, not a knoppmyth/mythbuntu issue)<br><br>reconfigured LIRC for my MCE remote and blaster, and then copied over my custom config files, and channel changing script.<br>
<br>Installed NFS and Samba, and recreated the network shares. Mythbuntu's defaults are different to knoppmyth's and I wanted to keep as was.<br><br>The box is actually quicker and more stable than before. Oh, and I have now got my frontends booting diskless over the network, which I never got to work in Knoppmyth.<br>
