How to correct install jira itsm 10.3.18 after 10.7.4?

If I understand your question, you upgraded to 10.7.4 and now you want to downgrade to 10.3.18. If that is correct, you would need to have a backup of your earlier database in order to downgrade. You can look at this link for more information: Rolling back a Jira application upgrade | Administering Jira applications Data Center 10.7 | Atlassian Documentation

Hi @Tony Montana ,

In most cases, you can’t just install Jira ITSM 10.3.18 over 10.7.4 and expect it to work correctly. Once 10.7.4 has updated the database and home data, going back to 10.3.18 is usually not a simple downgrade.

The proper way to fix it is to restore your database, Jira home, and install files from backups taken before the upgrade to 10.7.4.

So the short answer is: if you need to return to 10.3.18, the safest path is a full rollback from backup, not a reinstall over the top.

If you do not have backups, I would be very careful and contact Atlassian support before trying anything else.

If this helped, please give it an upvote.

@Himanshu Tiwary It is far more complicated to downgrade if you don't have a backup of the database. There is a value in the database itself that will prevent you from starting up a lower version Jira and connecting it to the database. It will reject that connection and give you an error message. You also need to update the dbconfig.xml file, which is another complication. 

@Tony Montana If you are comfortable making changes directly to the database and the dbconfig.xml, it may be possible to downgrade, but it depends on whether there are schema changes to the database that cause 10.3 to fail. 

The bottom line is that without a 10.3 or earlier backup, it will be very difficult to make this work.

Hi @Derek Fields _RightStar_ ,

That’s a fair clarification, and I agree the situation becomes much more difficult without a proper backup.

My main point was that this should not be treated as a normal reinstall or simple rollback. Once Jira has been started on the higher version, you cannot just put the older binaries back and expect it to work. As you mentioned, the database version check will block startup, and even if that is bypassed, there is still the bigger risk of schema or data changes that the older version may not handle correctly.

So for @Tony Montana , the safest answer is still that a downgrade to 10.3.18 should really be done using backups taken before 10.7.4. Without those backups, it moves into unsupported and risky territory very quickly, especially if direct database changes are involved.

Thanks for adding that detail.
