Upgrade error message
Asked by Thomas Berger:

|---|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|   | Upgrade failed. Please consult the system logs for details. You will need to fix these problems, restore your database and confluence home directory to the pre upgrade state. Then retry the upgrade. Upgrade error message: Upgrade task com.atlassian.confluence.upgrade.upgradetask.PopulateLowerFieldsUpgradeTask@3dd836e2 failed during the SCHEMA_UPGRADE phase due to: StatementCallback; bad SQL grammar \[drop index s_lspacekey_idx on SPACES\]; nested exception is java.sql.SQLException: Cannot drop the index 'SPACES.s_lspacekey_idx', because it does not exist or you do not have permission. Your server id is: **B0B7-71VE-QNWZ-PLH0** |

I'm testing upgrading v5.9.14 to v6.4.1 to no avail. Any hints why the SQL error is triggered?


Answers:
author: Damien Tan
body: Hey Thomas,

The index **s_lspacekey_idx** is being introduced from Confluence 5.10 onwards so when the Confluence 6.4 upgrade trying to drop it, it will fail (as the index does not exist).

try this upgrade path: 5.9.14 \> 5.10.8 \> 6.4.1  
this should be alright.

<br />

Note: You'll need to rollback to the working 5.9.14 first before upgrading again.

comments: author: Ankit Mathur
body: Shouldn't this be mentioned and highlighted in the Upgrade notes? The fact that the upgrade path from 5.x to 6.x is not direct, is not mentioned anywhere in the documentation, as far as I looked.


author: Chris M
body: The documentation is still incorrect. Please change the Upgrade Path section of the latest documentation. It currently says If your version is 5.0 to 6.x, "upgrade directly to the latest version". We tried that last week and and it failed because of this issue. <https://confluence.atlassian.com/doc/upgrading-confluence-4578.html#UpgradingConfluence-1.Determineyourupgradepath>


author: Ankit Mathur
body: Three years later, it looks like there is no intention to update this.


author: Rob Horan
body: I am getting similar errors on upgrade - is this the same problem? Do I need to go to 5.10.8 first?

author: Rob Horan
body: Also, is the need to go to 5.10 documented anywhere?


author: Meetu
body: I am having issue upgrading from 5.8.3 to 7.4.7, do I need to upgrade to 5.10 first?


author: Thomas Berger
body: Yes, update to 5.10.x first

Cheers,

Thomas


author: Rob Horan
body: OK but why is it necessary to go to 5.10 first if its not documented? If it is necessary why isnt it documented?

Basically, why has the documentation failed?
