After upgrade to 2025.6.0, files prior 2025.3.0 (v8) can not be opened anymore

Hi,
im using the local docker version of onlyoffice, after upgrading from 2025.3.1 to 2025.6.0, some of my onlyoffice files i created with 2024.12.0 can not be opened anymore. Reverting back to 2025.3.1, opening the file (which starts some kind of upgrade process), and then going to 2025.6 allowed me to open it again, so i need to migrate back, open each file at least once with 2025.3.1 and then upgrade to 2025.6 .. but i can not do that for my other members.

In the browser i get error 404 when trying to open the old document with 2025.6
404: https://my.cryptpad.local/common/onlyoffice/dist/v7/web-apps/apps/api/documents/api.js?ver=2025.6.0-1754027552850

in cryptpad logs i get:
["INFO","2025-08-01T07:18:42.930Z","HTTP_404","/common/onlyoffice/dist/v7/web-apps/apps/api/documents/api.js?ver=2025.6.0-1754027552850"]

i looked in /cryptpad/www/common/onlyoffice/dist .. there is no v7 ... but this also seems to be the case in v2025.3.1 .. so i assume some kind of bug in the converter or configuration refering to the wrong version on old documents?

Thank you for any hint on howto solve that!

Hello!

As mentioned in our Administrator Guide, we recommend to upgrade each versions one by one. For example, coming from 2024.12.0, you'll need to do:

2025.3.0
2025.3.1
2025.6.0

See: https://docs.cryptpad.org/en/admin_guide/maintenance.html#upgrading-cryptpad

If you skipped some updates in the middle, issues are to be expected.

Okay,

I have a backup from then, i will verify that!

but im pretty confident i did that, because usually i upgrade a few days after a new version is released, because out of feature curiosity.

Anyway, .. i can not guarantee to always touch/open all files in between upgrades, i have a few of them, even older ones i had not touched, and i had not any troubles till now, but it might be out of sheer luck.

Is there a way to trigger a document upgrade on all files for all users after an upgrade?

Thank you!

hirsebrei Is there a way to trigger a document upgrade on all files for all users after an upgrade?

Nope, as every document is end-to-end encrypted, you must own the encryption keys to access it and perform any operation on it. 🙂

Since i could not get around the thing, the only thing helped was, creating a /cryptpad/onlyoffice-conf/onlyoffice.properties and adding oldest_needed_version=v7 to it, before calling install-onlyoffice.sh.

Maybe it is because not persisting / caching the www/common/onlyoffice/dist/[...,v7,v8,x2t] in between upgrades, so it got thrown away after upgrades. The default in the installer is having v8 as oldest_needed_version when using v2025.6.0 .

But now it starts converting v7 docs to v8.

Have a nice day! 🙂
