Database migration issue in jira

Question

Hi All!

I have recently upgrade jira from version 8.9 to 8.20.10. After upgrade when i tried to link jira with my existing external oracle database (type -10g version- 19c) which we were using with older version of jira. It gave me error like the database is not empty or already in use. Then I manually copied dbconfig.xml file in my jira-home directory and restarted my jira datacenter server. It started fine after that. But now I cannot see some issues and filters in Jira board. Can connecting jira database manually like this has caused this issue?

if yes! How can i connect database with this newer version to make this work. What should be the standard way.

any kind of suggestions are much appreciated! 
thanks in advance! :)

Regards,

@Rashmi you are correct that will not get the results you want.  I would suggest following the upgrade steps again.  If you follow all the steps the DB would be upgrade on startup.  https://confluence.atlassian.com/adminjiraserver/upgrading-jira-manual-938846939.html

Hi @Brant Schroeder

I see this error when i try to do database setup manually with my own oracle database-

You have specified a database that is not empty, please specify an empty database. If you want to upgrade an existing installation

I do not understand why they want empty database when I want to use same database which i was using with older version database is on version 19c which is compatible with version  8.20.10 of jira.
