Moved my Nextcloud instance and Collectives don't decrypt

I’ve moved a long standing Nextcloud install to a new machine, and it all seams to have worked fine, until I went to Collections. All the old entries are encrypted still and show.

HBEGIN:oc_encryption_module:OC_DEFAULT_MODULE:cipher:AES-256-CTR:signed:true:useLegacyFileKey:false:encoding:binary:HEND

I’ve tried recover.php from encryption-recovery-tools/server-side-encryption but see “skipping this file because the filename structure is unknown…”

I’ve also tried “occ encryption:decrypt-all”

It seams the same as : New collectives are encrypted, but not decrypted But there is no solution there.

Any ideas?

I´d think, you habe to download your collective and extract it to the new directry. My expertice. I love the collective-app! Try and give an comment!

I don’t really have the old instance readily to hand. I’d have to rebuild the install from backups. The old server was about a decade old moved between many machines and grown a lot of legacy. I finally got it all replaced and dismantled for the end of the year. I’m trying to avoid restoring it even in a VM (lots of disks). I didn’t notice this issue until too late.

I see there is keys for the files in nextcloud_data/files_encryption/keys/files/Collectives/

I had only just started using Collectives, so there is only a few pages, but they were useful. Surely there is a way to get these decrypted. I have the files and the database, everything should be there right?

My best expirience → make a new instance, try to transfer your data.
