The migration process will anyway need to decrypt and encrypt everything, whether that’s done during the package upgrade process, or by the admin later (meaning that the encrypted data will be unavailable until then, and that might even get worse if some data get uploaded in the mean time). A previous proposition was to decrypt the data in preinst (i.e., using owncloud 7), then to enable it back in postinst, or later via admin action (but that could expose data to third party). At least that might workaround upstream migration issues, but the decryption part might not be possible anyway (e.g., an admin probably need to have set a recovery key, every user must have accepted this recovery method, and the recovery key password must be handy during the package upgrade).
