Is it OK to overwrite/update Calibre for large version jumps?
Is it safe/appropriate to update Calibre from version 5.44 to 7.17.0 on Linux by just overwriting the existing 5.44 install using the normal wget method? That's kind of a big version jump and I don't want to accidentally damage my library or mangle existing settings due to some incompatibility. I realize that I would/should have to download and reinstall newer versions of plug-ins.
I have always overwritten older versions in the past - never encountering any problems - but never for a version jump this large (two major releases). I do remember a large Calibre change in internals in the past, but I think that was between version 4 and version 5 (?) I don't remember that causing problems in Calibre itself, but there were problems with the DeDRM plug-in (probably others as well) until they were updated to work with the new Calibre internals. My library and settings are backed up and I could restore that if there was damage, but I'd rather not have to do this if it's a known thing that overwriting large version jumps is not proper upgrade protocol. Thanks in advance for any replies. |

I would make sure you have a good backup of the library and configuration files before doing the update. I have jumped multiple versions in testing without issue but always feel happier if I have a backup. As the old IT saw goes, the best way not to need a backup is to have one.

IIRC Calibre detects Library schema changes and UPDATES it.
That said, Those changes now make it difficult to revert (use) to an older version of Calibre. Heed the Backup advice (You really should be doing that already ![]() ![]() ![]() |

Out of curiosity is the old install from the distribution's repository or from a manual install?
If the repository I'd suggest an uninstall via the package manager followed by the manual install Sent from my Pixel 7a using Tapatalk |
