Troubleshooting Upgrades
Troubleshoot the issues you find while upgrading to the latest MySQL version.
Resolving Upgrade Failure Issue
You cannot upgrade a DB system to the latest MySQL version when there are insufficient IP addresses to maintain and upgrade the DB system.
Using the Console
Use the Console to resolve the upgrade failure issue.
This task assumes the following:
- The affected database is in active state but is not upgraded to the latest version because all available IP addresses from the customer subnet have been allocated.
Note
HeatWave Service requires two IP addresses per DB system in each subnet; one to attach to the DB system, the other for use in the maintenance and upgrade operations on that DB system. Also, the Networking service reserves three IP addresses in each subnet.

Do the following to resolve this issue:
- Create a full manual backup of the DB system. See Creating a Manual Backup.
- Once the backup is complete, do one of the following:
- Open the subnet and edit the subnet mask to accomodate more IP addresses. See To edit a subnet.
- Restore the backup to a new DB system and select a new subnet with a larger IP range and then delete the failed DB system. See Restoring From a Backup and Deleting a DB System.
