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.
