Upgrade Failed from 6.x.xx to 7.13

[Vijay Atturu]

Error:

Pre-upgrade validation failed. Check the Confluence application logs for more details. You'll need to fix these problems and restart Confluence before you can upgrade. Upgrade error message: Cannot update schema.

My System Details:

Service Machine OS: Windows Server 2012 R2

SQL SERVER: SQL Server 2012

Adding to what @Robert Wen_Cprime_ @mentioned, there’s a similar issue resolved in the past here: https://community.atlassian.com/t5/Confluence-questions/Upgrade-error-quot-Cannot-update-schema-quot/qaq-p/1447833.

I will suggest having a look at it.

Thanks Ismael, I was able to solve my problem with your link.

According to the system requirements for Confluence 7.13, your MSSQL needs to be at least at 2016.  You should upgrade that before upgrading Confluence.

Now, how do I rollback to previous working version 

[Robert Wen_Cprime_]

I'm not following.  My impression is that Confluence failed to upgrade.  You're still on 6.  Are you not?

[Vijay Atturu]

Currently it is not working. I am not sure what went wrong. Please see attached log:

Without knowing more details of what you did, I'm not sure I can advise anything more than possibly restoring the installation, attachments, and database from backup.

[Vijay Atturu]

We have tried to upgrade to latest version of Confluence on Windows Server 2012 with SQL Server 2012. And the upgrade process has been failed and currently the application is down. Let me know how to send you the log files.
