How To Restore After Upgrade Failure And Not Able To Access Admin

Attempted to apply upgrade from 4.10.X to 4.11 today. Upgrade aborted issued error message:

Tech details: Couldn't complete migration 20190814095620_core_ult_link_payments_and_shippings.php. Reason: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ' 4)' at line 1.

Completed migrations: 15 out of 34.

Attempted to do restore to get stores back online however not able to log into Admin keep getting Store Closed message. Is there a way to get around the store closed and be able to access the admin and restore or is there a STANDALONE PROCESS to restore data?

Hello

If you know how to use phinx on the console, you can do the migration yourself. Have you made a copy of the store and database?

Best regards

Thanks, Robert, we were able to locate the restore email from CSCart and that got us back online. Still having problems with upgrade

Hello

In file /var/upgrade/core_log.txt you have information on what was the problem during migration. This issue should be resolved by another attempt. If I were you, I'd make a store developer copy shop and try to upgrade there, solving migration problems (maybe there is only one problem or maybe more) and if you manage to go through the whole process then do it on the production shop.

Best regards
