Long story short, I would like to move recordings from one myth installation to another and need some help.

I have R5a26(myth A) on a drive that I would like wipe and integrate into my r5c7(myth B)install. However there are a number of recordings that I would like to selectively move over to the r5c7 install before I wipe the drive.

After reading the following forum posts:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=13329&highlight=merge+databases
http://www.mysettopbox.tv/phpBB2/viewtopic.php?t=10195&highlight=merge+database

I have a better idea of what needs to be done however I am still unclear on many steps.

Since I am not going to be doing a new install do I just need to move the nuv files and sym links over while preserving ownership and permissions?

Also I am not sure I follow the SQL myphpadmin part. I thought I had better ask for some help after reading the warning:

Thanks

Read the MythTV docs.... This is covered.

The other option would be to copy the files out of the Pretty directory and then put them into the Video directory of your other box.

Thank you both for your contributions and taking time to reply.

Yesterday I may have done this completely wrong, so don't do this unless it has been blessed by someone who knows more about this than me, but so far it looks like things worked.

Backed up both old and new databases with mythbackup

I moved the contents of the pretty and tv folders:



Then, I followed the instructions from the mythtv docs under section 23.7 http://www.mythtv.org/docs/mythtv-HOWTO-23.html#ss23.7
While it looked like all the old recording info made it, there were no previews for the old recordings nor could I watch them. Did a google and noticed something about blank basenames. Sure enough the old recordings had blank values in the recorded table's basename column. I don't know if I missed something or if this was just a result of moving nuv files in the format of chanid_startime_endtime.nuv ie 1046_20060123113000_20060123120000.nuv to my current version which uses chanid_startime.mpg

I ran the following update:
Then truncated the filenames and changed .nuv to .mpg in /myth/tv folder. ie 1046_20060123113000.mpg. There is probably a real slick way to rename these in one line with regex but I did them by hand.

I still have the old myth install intact and I have backups of the databases in case I really fubared this.

For reference the Pretty folder is simply symlinks to the TV folder with easy to read names.

Girkers, What is the trick to copying the symlinks in the PRETTY folder and getting the actual files they point at to come along during the copy process?

You see, I've tried to copy items from the PRETTY folder from both a Knoppmyth command line and using the Linux xfe graphic file browser loaded on the Knoppmyth machine and all I ended up copying were the simlinks - no video files.

Hi Eric,

The /myth/pretty symlinks are generated every 15 minutes (I think) as a cron job by matching up the file names with the real names in the database.

They are regenerated regardless of whether they already exist.

Yep. I am familiar with how the symlinks get in the PRETTY folder, but that wasn't my question.

The nuvexport utility has a mode specifically for this which dumps the SQL needed to import the file into another system.

Let me preface this by saying there are many ways of doing what you want to achieve. My suggestion is simply that, my suggestion.

Any way the reason your cp command didn't follow the symlinks is you specified the -a command. The cp man page states this:

So when you specify -a one of the options you are specifying is -P which tells it not to follow symlinks.

To copy the file a symlink refers simply use the cp command and no options and you will be right to go.
