I would strongly suggest performing a compatibility check and environment analysis to verify if your current application environment is fully compatible with what is required by the targeted Jira version.

• Database version
• Java version
• Plugin/apps version

Kindly ensure you understand what are the modified/customized changes in your Jira application as well to the compatible changes being carry forward to the new targeted version.

Jira v7.6.x to v.8.5.x is a major version upgrade. Even though your Jira instance is on DC, it does not support the downtime upgrade.

Lastly, always ensure there is a backup created before you proceed with the upgrade.

Kindly refer to the following doc for full guidelines and items to take notes while upgrading Jira DC.
