Upgrade confluence 5.10.1 to 6.6.2
Asked by Jonnada Kiran:

We are planning to upgrade our confluence from 5.10.2 to 6.6.2. I have read all the upgrade guide provided by atlassian. But, I didn't understand how to setup the synchrony. Can any one explain or give steps to setup synchrony in confluence datacenter?

body: Hello,

Synchrony will run as its own service separate from Confluence. You can do this in a totally new cluster (separate nodes), or you could run Synchrony alongside Confluence, in each of your four nodes. Synchrony will connect to the Confluence database to read/write content.

I would recommend creating a "synchrony" folder in just one node to start with. This can live in the same folder where your Confluence install is. This will be the folder from where you start Synchrony and where you have all of the configuration/jar files/drivers needed to run the Synchrony service. You can use any folder location you'd like, it doesn't have to be in any specific location.  
?? One thing to note - the synchrony-related files will not be in your 5.10.1 instance. You will have to upgrade to 6+ or just install version 6+ to be able to find these files and put them into the Synchrony folder.

<br />

**Setup**   
Once you have a Confluence 6 install folder, you can copy the entire "/synchrony" "folder from under \<**confluence_install\>/bin/** to the new location of your choice, the \<**confluence_home\>/synchrony-standalone.jar** file, and the database driver from **\<confluence_install\>/confluence/WEB-INF/lib** to your new /synchrony folder. You can then edit the **start-synchrony.bat/.sh** file and follow the instructions in the file to fill out your configuration for Synchrony. For example, if your database driver file was copied to **/opt/atlassian/synchrony/ojdbc7.jar** , your **DATABASE_DRIVER_PATH** in the *start-synchrony.sh* file will look like this:

```

DATABASE_DRIVER_PATH="/opt/atlassian/synchrony/ojdbc7.jar"

```

The comments in the start-synchrony files should tell you what to do, as there are several variables that need to be configured, but let us know if you have any questions on specific parameters. I hope that helps. ?

body: It's great to hear that you are planning an upgrade.

I understand you are setting up Synchrony for Data Center and are not sure of the steps. Is this one of the guides you already saw: [Configuring Synchrony for Data Center](https://confluence.atlassian.com/doc/configuring-synchrony-for-data-center-858772125.html) ? We also have this doc specifically for Data Center, which has the Synchrony node setup steps: [Upgrading Confluence Data Center](https://confluence.atlassian.com/doc/upgrading-confluence-data-center-1507377.html)

Based on the documents, please let us know which part is hard to understand as this can help us with our documentation and of also help me research the specific steps that you need to know.

In our organization we have four confluence nodes. I understood rest of the steps except the above one. Where I have copy these files and what i have to edit in start-synchrony.sh. How to configure this for all the four nodes.

body: Hi Jonnada,

I opened a support request on your behalf so we could help you offline. You should see an email from the support portal soon.

When it is resolved, we can circle back to this thread, in case something is explained in the ticket that we should share with the Community.

Thanks,

Ann

body: Hi Ann,

We are planning on doing the same upgrade, is there anything else that we should be aware of from your discussion ?

Best regards,

body: Hi Florian,

If it is a Data Center upgrade you will be better off [opening a support ticket](https://support.atlassian.com/contact/#/) using your Data Center license because there are a lot of variables and you will want to share your logs and configuration details with the support team. Our support portal is equipped to do that whereas this forum is more suited for Q and A.

If you are upgrading a standalone instance, please review [Upgrading Confluence](https://confluence.atlassian.com/doc/upgrading-confluence-4578.html). If you run into anything in the docs that you have questions about, please post a new question on the forum. People who are searching for questions to answer frequently filter by unanswered so if you reply on this thread it will be less visible.
