Questions on calibre migration
Hi Kovid, on migration to another computer I used the Export/Import function, which works in principle very well
I really liked it to find all my settings and saved searches. However (there is always an however ) I encountered some points I like to have clarified.
I used calibre 3.30 32bits (source) and calibre 3.30 64bits (target). Last edited by DrChiper; 08-24-2018 at 08:42 AM. |

Ok, I could find no way to fix this via calibre: at least I could not find it.
So this is what I did:
Summarizing,
I'm not sure whether this behavior is due to my handling, or some oversight, or that this is erroneous behavior of calibre. Anyone? Last edited by DrChiper; 08-24-2018 at 02:56 PM. |

I've never used the import-export function, and I've moved my libraries to new computers at least three times. I always copy my libraries and the configuration folder manually to an external HD and from there to a new computer. Works like a charm. Nothing has ever been lost, all the plugins, settings, preferences have always been intact.

I've used the export/import feature without any issues. In two instances between different operating systems, Windows->MacOS, and Linux Mint->Windows, the other two were Windows->Windows. I've also provided guidance to a couple of people over the phone when they needed to use it, again with no issues.

Import does not re-create the full path to previous libraries, it only preserves the library name. This is because there is no guarantee that the full path is valid on the new computer. You can always rename the libraries/move them manually after import if needed. The important thing is that *all* the data is preserved.
I'm not sure how you ended up with paths as library names, but I cannot reproduce that. |

Well, the problem is that not many persons probably do use the migration functions export/import much, so it is not tested that much.
Further, I used calibre a long time on my old and trusty machine, starting with version 1.x or so. During all those years derelict and obsolete files seem to clutter the calibre environment as I noticed when inspecting and comparing old and new directories. So a fresh new start from time to time is never a bad thing IMHO. Quote:
I did a compare between the original directories and the new ones and noticed that all files are present on the new computer, minus file "metadata.opf". The latter was missing for all entries. No idea whether that file is important, can be recreated or is now obsolete. Quote:
At this moment calibre 64bits seems to work happily on the new ridiculous state-of-the-art machine using the old libraries. Even without those missing "metadata-opf" files. |

metadata.opf is a backup file that is not needed for normal operation and it will be regenarated automatically over time in your new libraries.
