Entire Library Gone! Please help!

@Charles > Did you use File > Library > Backup Library on the old one and File > Library > Restore Library on the new one? I'm guessing not if things aren't loading. Chances are you copied the rekordbox folders and expected everything to work, but neglected the fact that your username(s) on each machine are different, thus the paths in each setting / data file / database are not the same, meaning rekordbox can't find what it's looking for.

No I tried to follow the video on migrating my library. The only thing different that I did was instead of using an external drive I put the new computer in Target disk mode as a new drive and moved the library. Current status is an empty library on old machine but my music folders reside on both machines. I have music in both places but now library contents in Rekordbox :( Gig tonight.

I moved the library so it maybe on the new machine somewhere its just not detecting it. 

Yeah, moving it like that is not the intended method of my migration video. That "move" still expects you'll be using it from that external location, not locally.

I'm sorry that this would come after your gig, but I can still try to assist you in resolving the missing contents.

Hi,

Thank you for responding. After Time Machine Backup's and lots of messing about I've managed to get my new library on the new Machine minus playlists from a few weeks ago. At this point I'm fine with that. Restoring has not been fun. Although it managed to seem to save my cue points everything is wonky. I had to re align grids, move stuff on beat and when I played the other night some tracks are 2 BPM off as they read. I noticed it while mixing. Also the grid does not sign up on some tracks. I can set A nice and tight and then the grid is way off when trying to set B. Now the entire library is wonky. Not the most fun experience and I have more gigs this weekend. In the past I have always done a time machine back up and have had a second machine but now I am consolidating to one machine. Any help would be greatly appreciated. 

Wow, sounds like you've made a real dog's breakfast of things! What I would suggest, and possibly the the best thing you could do, would be to restore your database back to the original computer, then make an export, either to external drive or as a backup. Using the external drive method would allow you to use it with multiple computers and always have your data in sync, but then it's only on that drive so it's imperative to keep a backup copy somewhere.

Yes I did that. I exported library from my Original Database and Imported it on the new machine. 

Okay, so where are you at now... still missing files? Waveforms? Cuepoints?

Hey! Thank you for checking back with me. I have my entire library. Unfortunately it's been a pain staking process having to redo the grid on half the tunes. I migrated the library 3 times and always came back to the same issue. Cue points were set but the grid would be off. So, essentially I have to go back through and re do all the cue points. Wish this migration was easier. I am pretty tech savvy and I tried everything.

lol - I hate to disagree with you, but the "tech savvy" comment made me laugh just a bit. If you were moreso, you wouldn't be in this situation! ;)

I've done the migration numerous times (for support) and never experienced what you've described, so the only conclusion I can come to is a mis-match of rekordbox versions (like a serious version change; tracks were originally analysed pre-4.2.4 and never updated), or data files were damaged.

Sorry for my delay I have been busy redoing my entire library. I hate to disagree with you and your response. The least you could do is show a bit of empathy instead of laughing at me? Funny 2 days before I launched this thread I spent $2,200 on a new 900 Nexus mixer so you can imagine how taken back I was to read your response especially after being quite polite and thanking you for your help. I am a long time customer and user of Pioneer product and have spent many thousand's (I'm sure you've heard that a few times). Thank you for all your help. Luckily I mustered up enough skill to figure it out. I guess if you were "moreso" yourself you may have been able to trouble shoot my issue.

Charles, I'd love to help you out, but unfortunately you've posted several times stating you've tried different things:

1) You moved the database to an "external drive," per my video instructions, but instead of using an external drive (as recommended), you put computer B (the new destination) in "target drive" mode, which wouldn't configure the database and supporting files properly.

2) You did a Time Machine restoration and "lots of messing about," but I have no idea what you did there. Did you restore from the old computer and then copy it over to the new one and try to load it directly there? Did you edit any of the supporting files to tell rekordbox the location of the new files? Did you relocate missing songs within rekordbox?

3) You say you "exported library from my Original Database and Imported it on the new machine," and then you say you "migrated the library 3 times" but still had problems with "Cue points were set but the grid would be off." A proper export and import, done following either my instructions in the video or the official rekordbox instructions on creating a backup and restoring it on a second computer would result in all of the waveforms and grid points being accurate. Each song in your database has a unique identifier and that ID matches grid & hot cue data stored in a separate file. It doesn't drift or get skewed because it's on a new computer, the only possible way it can be lost or damaged is if the ID is different and it's somehow loading the grid & cue data for a different song.

I wasn't laughing at you, more of a situational chuckle at your comment about being tech savvy. As I said, if you were a bit more savvy, you wouldn't be in this mess. The process isn't difficult, but it seems to me that you've made it so by deviating from the recommended steps and processes.

I'm glad you were finally able to figure it out, perhaps next time seek the advice before hand: "Hey, is if a good idea for me to put my new computer in target-drive mode and try to move my database that way?"
