Upgrade error

[SWR Recv]

Trying to upgrade confluence server to confluence data center and there is an error saying : 

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. 

Please help!!!

Hi @SWR Recv 

Have you followed this doc to migrate the instance

https://confluence.atlassian.com/doc/migrate-from-server-to-data-center-203651.html

Thanks,

Hi Pramodh, 

Yes we tried to follow that but that didn't help much! I had existing confluence server but this one has a license that has expired. Now I was tried to update the license with a new license that I have which is a new Confluence data center license and this is prompting me to migrate but then when I attempt to follow the steps, it failed at the pre-upgrading validation with the error mentioned above

Thank you

I would like to add that I am trying this in the air-gapped environment (non-internet environment) using the confluence installer file

Another question : is  SQL server 2019 compatible with Confluence 7.16.0 ?

if not, which confluence version compatible with  SQL server 2016 ? 

Thank you
