I have a working 12.04 ubuntu /27.3 myth system on a 1TB drive and a second 1TB drive with mythbuntu 14.04 installed and updated. What is the easiest way to get all the settings and configurations including channel lineups onto the new system? How much comes with a database restore?    Daryl

Theme files are not in the database and IIRC you can have a minor hiccup if the theme your old system was using is not present on the new system when you start up after first restore. It's not a big issue (I think) but best to probably make sure your theme is present and working on the new system (with clean empty default database) before restoring the old database.

While YMMV I have used the Ubuntu upgrader on a BE and a FE to get from 13.xx to 14.04 with no notable issues. One had to go through a couple of steps I think (13.04 to 13.10 then 14.04 IIRC) but still worked.

Each time the upgrade completes the ensuing reboot fails.  So I'm trying a clean install of mythbuntu, hostname is the same and the theme is the same and that is all I've done so far. So the next step should be to move my /usr/local/bin directory over and recreate my udev rules then restore the database?   Daryl

About the only thing I can think of that might be a problem would be whether mythcommflag is entered as "/usr/local/bin/mythcommflag" or "mythcommflag" and either way we can just tweak it up later if it doesn't work. Both old and new install are variants of Mythbuntu anyway (IIRC) so it's pretty much a given it will work fine without any intervention anyway. It would be more a (minor?) consideration if you were moving from say Mythbuntu to Gentoo or something else - I probably shouldn't have mentioned it in the first place it is so unlikely.

Ie add a single tuner in mythtv-setup, add a video source etc and check that you can get some live TV, program guide etc. That might shake out a few issues first (MySQL setup / MythTV user setup / various permissions - which should all be fine out-of-the-box with clean Mythbuntu install) with a known clean database so that future troubleshooting is kept as simple as possible. Make sure this step includes the config.xml file from the old setup (ie hostname identifier, username and password in particular).

I think storage group folders can be corrected after that if necessary if folder naming or mount points have changed.

Check mythweb at the clean install stage as well, that can be a common source of hiccups. Best that it is working before database restore.
