Problem with migration confluence to cloud

Question

Hello.
I want to migrate Confluence to Cloud but I get an error during the migration.
I searched the internet, there is one solution but unfortunately it didn't help.

what have i tried?
Reconfigure MySQL (Point 2 of https://confluence.atlassian.com/doc/database-setup-for-mysql-128747.html)
Solution from post where was my problem (https://community.atlassian.com/t5/Confluence-questions/Can-t-edit-my-pages-or-edit-any-thing-Emergency-help/qaq-p/1613024) - not working for me

What error am I getting?

Failed to export [cloudId=6fa4179d-06fd-4714-b8e8-a1ae956b51ed,fileId=4208cd96-996f-4984-b635-db0f7109cf92,spaceKey=KOM]. Error: Hibernate operation: could not execute statement; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: PROCEDURE wikidb.content_procedure_for_denormalised_permissions does not exist

Please, can u help me?
I can't create a support request because the license for the server version has expired, so I want to switch to the cloud

Thanks for your answer, but even after doing this solution, it still didn't help me.
But it led me to what could be wrong.

When I imported a database dump into a database called 'wikidb', procedures were not imported.
After importing to the newly created database: 'wiki', the procedures were imported and successfully migrated to the cloud

Ok, this is a known bug in Confluence, and it can be fixed by following https://confluence.atlassian.com/confkb/confluence-mysql-database-migration-causes-content_procedure_for_denormalised_permissions-does-not-exist-error-1072474724.html

System admin -> Migration Tool -> Create new migration

Users migration successfull
