Synology owncloud hazardous status (failed package migration from v6.x to v8.x)

[farpet]

Steps to reproduce

1. Updating ownCloud to version 8.1.1, from v6.x
2. Exception: Updates between multiple major versions are unsupported.
3. The update was unsuccessful

Expected behaviour

Tell us what should happen : I expect migration successful ?

Actual behaviour

Tell us what happens instead
Exception: Updates between multiple major versions are unsupported.
The update was unsuccessful
when I migrated to DSM 6, owncloud v6 stoped working,
inadvertently I clicked on migrate to owncloud v8 what I didn't want to do before an export :(
and
http:///owncloud/remote.php/carddav/addressbooks//contacts/
https:///owncloud/remote.php/caldav/calendars//defaultcalendar
doesn't work anymore :(

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';
MySQL returned an empty result set (i.e. zero rows)


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

@farpet Please close here and follow the instructions in:

https://central.owncloud.org/t/updates-between-multiple-major-versions-are-unsupported/815

how to do a correct upgrade. If you need further support on how to do a correct upgrade please create a new thread at central.

You should also contact Synology and make them aware that their users can't upgrade directly from oC 6 to oC 8. Skipping major releases like 7, 8, 8.1 and so on is not supported.

[farpet]

So what to do to at least extract data ? I still have access to DB,
can I export manually (SQL, PHPMyAdmin) my Contacts and Calendar items, for e.g.: I just need to export : SELECT fullname,carddata FROM contacts_cards WHERE addressbookid=3 ORDER BY contacts_cards.addressbookid ASC

thank you in advance

[ghost]

As advised please ask such questions at central. As you have already asked it there have some patience until some one is answering it: https://central.owncloud.org/t/owncloud-sql-manual-export-to-vcf-ics/1500

A short term measure is to revert to your backup and do the upgrade step by step as described in the linked FAQ.
