Hi everyone,

I'm trying to migrate from a Kobo Clara 2E to a Kobo Clara BW while keeping: reading stats, collections, annotations

All of my books are sideloaded (mix of EPUB and KEPUB). Around 1000 books.

From Kobo Clara 2E Firmware: 4.38.23697 to Kobo Clara BW Firmware: 4.45.23697

Same Kobo account on both devices. I turned on the sideloading model for both devices.

I followed the first post of this thread: https://www.mobileread.com/forums/sh...d.php?t=336182

It seemed very successful at the beginning: All books, reading stats, collections and annotations were transferred.

However, even though I can see my old annotations in the annotation list, if I tap any annotation, Kobo jumps to the page and then the highlight disappears. Returning to the annotation list shows that all annotations have disappeared. After that, new annotations can not be saved as well. This happens for both EPUB and KEPUB books.

Factory resetting the BW restores normal annotation functionality.

I have been fighting it over with chatgpt but it couldn't help me at all. I decided to come back here for any possible solution.

Has anyone successfully migrated annotations from firmware 4.38 to 4.45 (Clara BW)?

Is the 2020 user-table migration still expected to work on recent firmware, or are additional tables now required?

Has anything changed in the annotation subsystem after 4.38 that would explain why old annotations initially appear but disappear when opened and prevent new annotations from being created?

Any guidance would be greatly appreciated. Many thanks in advance!
