What would you recommend?
If I simply copy the old library folder - at once or step by step - over but not the .db and .json file (these are provided by the fresh installed Calibre) and then point Calibre to the folder with the copied library would this prevent problems that could mess up the database?
It is a big library with 100K+ database etnries.

manawydan - I think you would need to rebuild the database via Library Maintenance->Library restore - that could take a quite a long time (overnight) if
"100K+ database entries" means 100,000 'books'. The database will be rebuilt from the .opf files in the book files. If the database is the source of your problems, then rebuilding it from the .opf could replicate the problems.
Have you tried rebuilding the database on the current library, if you have and it didn't fix the problems, then I doubt that copying the author and book folders elsewhere and doing the same thing will resolve your issues - unless you have hardware problems.
It might be better to say what you mean by
"my old db... acts more and more funny" - it could be the configuration data that's gone skew-whiff, rebuilding the database wont fix those problems.
Try renaming the config folder (with calibre not running) and then start calibre (it will build a fresh config folder) and point it to the existing library. You'll not have most customisations but it should be 'sufficient' to give you an indication of whether it is the library database that's causing your problems.
You can restore the old config by deleting the 'fresh' one and re-renaming the old one.
