I than decided it would be more useful if I use portable Calibre instead the one installed on my tower PC. So I installed a portable version onto the same external USB harddisk. It works on its own but it will not read from the library made by the previous standard Calibre. It declares it corrupt and it is unable to fix it. The same library is fully useable using the standard Calibre.

If I try to transfer individual books between "standard" library and a new "portable" one (using Add book function) none of the metadata are being transferred correctly.

Obviously the Calibre developers decided to use two mutually incompatible database formats for those two versions of Calibre.

Is there an easy way of transferring the standard version into portable version?

Are you using 'Copy to Library'?

There are steps that must be done when there are custom columns in the original.

1a) the Target must have the same structure.
You can easily create a NEW (empty) Library with the same structure by ticking the box 'Copy structure from current Library' in the Create/Switch form

1b) Use the OS to Copy the entire Library folder to the new location (same as you would for a full library backup)

2) review and adjust the Preferences:Tweaks:Control how Tags are applied when copying
