Upgrading from 6.15.7 to 7.13 (most recent edition)

[Casey Allen]

Hello, 

I am a new-er Systems Specialist tasked with upgrading our confluence internal server from 6.15.7 to 7.13 (most recent version).

However I have failed twice on installing. Unsure where I have issues on the upgrade process.

Specs:

• The Confluence is running on Windows Server 2016 standard within a VMware virtual machine (thank goodness for snapshots and reverting on failures).
• PostgreSQL server is at version 9.2
• Confluence Version is 6.15.7

My upgrade list:

• install postgreSQL version 11
  • create new DBs reflecting old dbs, and back up old, and restore into the new (having some cli issues with just using pg_upgrade)
• Downloaded Confluence 7.13 installer, and ran it in upgrade mode

My process:

• Make a snapshot
• Backup Confluence (This process takes like 1-2 hours 21gb of data)
• Install postgreSQL v11
• back up 9.2 postgre DBs
• create users in postgre v11 the same as the 9.2 users (there are only like 3)
• create new dbs in postgre v11
• restore old dbs into postgre v11 new dbs
• change ports of v9.2 DB from 5432 to something else, and v11 changed to the 5432
  • disconnect and reconnect DBs
• disable Confluence service in windows services
  • restart the server (the service does not stop 100% if I do "stop")
• install Confluence 7.13
  • select upgrade over existing and allow it to do the backup
• Process finishes (not sure, didn't check the log)
  • Apache runs at high CPU loads afterwards, unsure if I am supposed to wait a specific time frame.

My results:

• First attempt I did not upgrade the PostgreSQL and ultimately did not work
• Second attempt I upgraded PostgreSQL and I think properly migrated the 

Any input would be greatly appreciated, especially if I am doing something wrong.

Hi @Casey Allen 

I would recommend that you open a ticket with the Atlassian Support team on this link. They are very good at providing assistance on upgrades and they can do a review of all your procedures.  

Please Provide the following details:

• Summary - a short summary of your problem.
• Description - details about the problem. 
• Steps to reproduce – if reproducible, provide step by step detailed information
• Expected Behaviour – what was the expected outcome
• Severity - give an indication of how many users are affected by the problem
• Provide screenshots if possible
• Attach support zip - this will create a zip file of your logs and configuration files, these can really speed up troubleshooting your issue and should be included if possible.  See Create a Support Zip for info on what's included. Make sure you reproduce the issue before getting the support zip.
